There are several advantages to using an infrared thermometer over traditional models. Since these are digital thermometers they are often easier to read, which can also make them a little more accurate since you are less likely to make a mistake. Infrared thermometers are also faster, and when you are using it to take your child’s temperature the last thing you want to do is have to wait. If you are interested in infrared thermometers but aren’t sure what to look for the following tips can help you get started.
Regardless of the type of infrared thermometer you are looking for, one of the first aspects to consider is your budget. These models are priced higher than traditional stick thermometers, and deciding on a set budget can prevent you from spending more than you can afford. Deciding on a spending limit will also help you narrow down your options and make it easier to choose the best one for you.
It is important to pay attention to the quality of the thermometer. You can find some at a relatively inexpensive price. While these models might seem budget friendly, they are often inaccurate and can break easily. In most cases you will find that it is well worth it to pay a little extra for a high quality infrared thermometer that will provide you with accurate body or surface temperature readings for years.
Once you have decided on a set spending limit it is time to consider the type of infrared thermometer. While the different types of infrared thermometers might work in a similar manner, they are not all designed for use in the same applications. If you want to get consistent and accurate readings it is important that you choose the right one for the task.
Infrared thermometers are typically divided into three classifications, and since each is designed for a specific use one is not necessarily better than the other. Tympanic infrared thermometers are used to measure the temperature inside the ears, and they are designed to produce accurate readings in only a few seconds. While they are safe and fast, not everyone is comfortable have something put into their ears. This can be especially problematic with some children. The same is also true for oral thermometers, which is also why they are seldom rated in the product reviews.
Forehead infrared thermometers are generally preferred for body temperature readings over other models. Since they are designed to glide smoothly across the forehead they are often preferred by adults and children. Parents also appreciate the fact that they can easily take their child’s temperature without any fuss or problems. There are also no contact infrared thermometers and these can be used for several applications.
No contact infrared thermometers are used to measure surface temperatures. There are two red dots that eventually align so the device can accurately measure the temperature. They can be used to measure the temperature of almost any surface in the kitchen, including hot stovetops, ovens and even frying pans. Adding to their versatility, you can also use a non-contact infrared thermometer to take accurate body temperature readings.
Infrared thermometers can come with several convenient features, which are designed to make it even more convenient to use. Models that come with bright displays are easy to read in any lighting, and it’s a great function to have if you are trying to take your child’s temperature in the dark. Some models come with convenient alarms that will alert you if the temperature is too low or high. This can be particularly useful when you are monitoring a sick child or need to keep a pan at a constant temperature when you are cooking.
Buttons that are clearly marked are also appreciated, along with automatic shut off functions that help to conserve battery power. Since infrared thermometers do run on battery power you also want to make sure that they are easy to change. Otherwise you might be looking for a new one once the current batteries are dead. Another convenient feature to consider is a memory function. This allows you to save the last temperature reading which can be helpful if you are monitoring a fever. Some models also come with protective cases that also make storage a breeze.

Flowmeters – Buying guide & Comparison
If you’re short on time and you just want to find the best flowmeter, this short paragraph should help you get exactly the model you need. According to our research the Ameriflame RF2480-320 is the best because it comes with a durable brass body and fittings constructed from the same rugged material so rust and corrosion is never a problem. The large 1.5 inch gauge is easy to read so you can take accurate measurements the first time. To add to its ability to provide you with precise readings there is also a tube that is designed to be “self centering”. Not only is this device a flowmeter, it is also designed to be a regulator. If the Ameriflame RF2480-320 is not available your second option should be the Blue White 2”.
If you aren’t sure what a flow meter is, you are not alone. It is simply a device that measures the flow rate of a liquid or gas. There are several applications both at home and professionally where a flowmeter can be used, and there are also different types of meters to choose from. Finding the right meter for the job can be confusing, which is why we have included the following tips in our buying guide.
According to the best flowmeter reviews one of the first aspects to consider is the price. While the cost of the meter will often depend on the type, in most cases deciding on a set spending limit will help you narrow down your possible options. The price of the flow meter will also depend on its included functions and features, which means you can often find a basic model that is designed to fit most budgets.
The materials used in construction will affect its price, along with the quality of the flow meter. Some inexpensive flow meters might seem budget friendly, but if they are made from inferior materials they might not last long enough to be worth their low cost. This can also affect the accuracy of your readings which can result in expensive problems if the flow rate of a liquid is off. In most cases it will be worth it to spend a little extra money on a quality flowmeter.
When it comes to choosing the best flow meter you need to decide on the type. Variable area flow meters are the most common and can be used to measure liquids and gases. These meters are inexpensive, easy to use, and are often recommended for use at home. Spring and piston models are also incredibly simple to use, and are only priced slightly higher than ones that come with a float and tapered tube. There are also inexpensive gas flow meters which are designed to be used in specific applications.
If you are measuring the flow rate of wastewater you will probably want to choose an ultrasonic flow meter. Since you are not placing the meter is the potentially corrosive liquid you don’t have to worry about sensitive components being damaged. It should also be noted that these types of meters are priced a little higher since you are using ultrasonic vibrations to measure the flow rate of the liquid. Other types of flow meters designed for use with water include paddlewheel sensors and positive displacement models. If you are dealing with a straight pipe with gas or water a positive displacement flow meter might be the best choice for you.
If you are looking for an accurate flow meter that can be used with water and gas, you might want to consider a turbine one. In some cases you might need to measure conductive liquids, and a magnetic flow meter will usually provide accurate readings without any problems. You can also find several types of flow meters on the market that are designed to be used for specific applications, but these are generally intended for professional applications.
Once you have decided on the type of flow meter you will want to make sure that it is accurate. If the meter can’t accurately measure the flow rate it will basically be useless. Since there are several types of flow meters that can be used for the same applications, you can usually find one that is accurate and designed for your task. One aspect to consider is whether the flow meter comes with moving parts. Not only are these meters often priced higher than similar models, they also come with certain problems.
Moving parts are more prone to wear and tear, which means they can break without warning. In some cases a small piece can come loose, and you might not realize it until you notice your readings are off. Calibration is also more difficult when there are several moving parts and this will affect the meter’s accuracy. Another problem is that changes in temperature can cause parts of the flow meter to shrink or expand. When this happens parts can come loose, rendering the meter useless until it can be repaired. In most cases experts recommend choosing a flow meter with as few moving parts as possible, unless there is not another option.
If your budget will allow it there are a few features you might want to consider that can make the flow meter easier and more convenient to use. Large dials and digital displays are easier to read, which is always an advantage. Models that come with handy instructional manuals ensure that you know how to properly use the flow meter, and this is important if you want to be able to take accurate readings. You can also find flow meters that double as regulators, which is always a convenient option.

If the Eisco Labs Food is not available, your second option should be the American Educational Products Electric.
Whether you are studying to be a nutritionist or are looking for a scientific way to accurately measure the calories in your food, you need a specific kind of meter. A calorimeter measures the amount of energy released when food is heated so you can calculate the calories per gram. While this might sound a little complicated, in reality it is actually pretty easy. Before you rush out and buy one of these meters for home or school there are a few aspects to consider. In this buying guide you will find the information you need so you can confidently choose the best calorimeter in 2017.
As stated in the best calorimeter reviews one of the first aspects to consider is your budget, and this is true if you are a student or simply want one for use at home. There are several models to choose from and once you have decided on a set spending limit it will be easier for you to narrow down your possible options. One way you can save a little money is to avoid meters that come with a lot of extra features and functions.
While you can find calorimeters in a range of prices, you don’t want to try and save money by purchasing one constructed from inferior materials. The calorimeter will be used with heat, usually a flame or electricity, and one that is cheaply constructed can be dangerous to use. Not only can it be dangerous, but if it breaks after only a few uses it could become an expensive waste of money. This can also be true if you purchased one that is used.
It is not uncommon for people to wonder what the best type of calorimeter is, and the answer usually depends on how it is going to be used. There are several types of calorimeters that use different methods but all measure the amount of heat emitted. Two of the most common types are the coffee cup and bomb calorimeter, and both come with their own advantages.
The coffee cup model is simple and inexpensive, and some students can even make one in the lab. All you really need is a styrofoam cup and a steady heat source to place it over. You will also need an instrument to measure the effect of the heat on the various liquids. While this type of meter is effective, it can only be used to measure small amounts at a time. If you are serious about determining the amount of energy released to determine precise calorie counts you will probably want to spend a little more on a bomb style meter.
You can often find these calorimeters in a variety of sizes and since the chamber is sealed and placed underwater it is often considered slightly safer to use. While these calorimeters can cost a little more, you can find some marketed as kits so everything that you need to get started is included for one fee. In some cases this can actually save you time and money since you don’t need to purchase additional accessories. For more precise measurements using specific methods there are also titration and scanning calorimeters, along with isothermal microcalorimeters. It should be noted that these types of meters are typically only found in a research lab, and may not be practical for all applications at home.
When you are looking for a calorimeter there are a few other factors to consider. The weight of the meter could be important, especially if you have to carry it to class. The same is also true for the size, though most calorimeters measure less than 8 inches tall. This ensures that not only are they relatively easy to take with you, but that the meters will fit on crowded counters and work desks. It is also important to note the power source, especially since not all models are electric. If you do choose one that is battery powered you will want to make sure that they are easy to replace as needed.
Since you will be working with heat you also want to calorimeter to be insulated, at least on the handle so you can safely lift the lid. You might also want to choose one that comes with a convenient thermometer or else this will be something that you might have to purchase separately. Since you are trying to measure the calories in specific foods, models that come with a built in cork and nail. This will provide you with a place to secure the small food sample so the reaction to the heat can be accurately measured.

A barometer is designed to measure changes in air pressure so you can more accurately predict the weather. Anglers and gardeners often use these instruments, along with hikers and other outdoor enthusiasts who want to know if there is a chance of rain in the next few hours. You can also find several types and styles of barometers, which can make it difficult to choose the right one. In this buying guide you will find helpful tips that will make it a little easier to find the best barometer to meet your needs.
The best barometer reviews recommend first deciding on a budget. Having a set spending limit in mind will help you narrow down your possible options since there are several models to choose from. The price of the barometer is often reflected by its design and included functions so you can find basic models that will fit almost any budget.
When you are deciding on a set spending limit it is important to also consider quality. Just like an inexpensive watch some cheap barometers might not be entirely accurate. This could ruin your plans for the day. The last thing you want if you are trying to find the best barometric pressure for fishing is to purchase a model that can’t track changes accurately.
There are two main types of barometers, though some collectors state that there are actually three. Each has its own advantages, and often the best one for you comes down to budget and personal preference. The oldest type are stick or mercury barometers, and they are usually easy to read. As the mercury level rises and falls according to the air pressure a scale or dial with a moveable pointer tracks the changes. It is important to note that mercury is a highly toxic substance and these barometers might not be safe to use around small children.
Aneroid barometers are slightly newer and the name refers to its lack of fluid. Since there isn’t any mercury these barometers are considered safer to use. Instead of rising and falling levels of fluid, these models use a system of small springs. A small capsule is raised or lowered according to changes in air pressure, which is tracked by a needle. Since there isn’t any fluid to house and protect these barometers are often designed to be compact and easily portable.
You can also find pocket barometers which are great for hikers and fishermen. Since they are a type of aneroid they are often grouped together. The only real difference between a pocket and traditional barometer is generally the size, and a few extra functions on some of the higher priced models.
Regardless of the type you can find barometers that are designed to look great and match almost any decor. This variety in style and design is also what makes them collectible. The dials on mercury and aneroid barometers can be constructed from copper, silvered brass or even decorative paper.
The casing can also be constructed from a variety of materials which makes it relatively easy to find one that looks great in your home or office. Some of the most common materials include brass or other polished metals. You can also find casings constructed from oak or mahogany. When it comes to pocket barometers most are constructed from a lightweight and durable plastic to ensure that they are easily portable.
The design also refers to the shape and size of the barometer and most of today’s models are round. Collectors can still find stick shaped models, but they are not as common and all use mercury to measure air pressure. Round barometers are easier to mount on a wall, and some are even designed to be placed in a stand or dashboard.
Depending on your budget you can find barometers with a variety of features and functions, but regardless of your spending limit you want it to be easy to use. Dials that are clearly marked are easier to read, especially when the numbers contrast with the backing. You can even find models that are color coded which makes tracking air pressure changes a breeze, even for beginners. Small screws and knobs can make calibrating the device a simple task, and this is important if you want to accurately track changes in air pressure.
Pocket and handheld barometers that come with wrist and neck lanyards are always convenient, especially when you are hiking or fishing. Some even come with a protective case so it can safely travel with you.

If you want to accurately measure wind speed you will need an anemometer, and these convenient devices are not just for use at weather stations. It is important to note that while some anemometers may resemble a weather vane they do not measure the direction of the wind. If you are interested in an anemometer, but aren’t sure what to look for, the following tips will help you choose the right one for you.
One of the first aspects to consider, according to the best anemometer reviews is your budget. There are several types of anemometers to choose from and deciding on a set spending limit will help you narrow down your options. If you are on an extremely tight budget you can make an anemometer from common household items, but accuracy and reliability is a common problem.
You can find basic models that are priced to fit most budgets, and the majority of these devices will accurately measure wind speed. It is important to pay attention to the design and materials used in construction since this can affect its performance. The best cheap anemometer will still be durable and accurate, even though it comes at a lower price.
There are two main types of anemometers to choose from, and each comes with its own advantages. Your budget and where the anemometer is going to be used will help you decide which type is best suited for you. Weather station anemometers are often the highest priced, even though most are easy to use. These devices typically come with cups that spin when they catch air, and the number of times they rotate multiplied by four will give you an accurate wind speed reading. Most of these are designed to be mounted from a pole, but some can also be set up outside on a console.
Digital anemometers can vary in price, depending on the included features. Since these handheld devices come with a digital display reading the wind speed is quick and easy. A digital anemometer typically comes with a small fan that turns when it catches gusts of wind, and the device will track the rotations and calculate the wind speed for you. Since they are designed to be handheld these models are generally lightweight and easily portable.
Range and battery power
The range of an anemometer will vary and it is something that you will want to carefully consider, especially with handheld models. If you are shooting and need to measure the wind speed at the target you will need one that has a longer range. Most experts recommend looking for one that comes with the range capabilities of at least 0 feet – 5,000 feet. This way you don’t have to stand in the middle of a wind gust just to measure its speed.
In general most anemometers are powered by batteries that will need to be replaced, unless you spend extra on ones that can be charged by the wind. Since these are expensive and often experimental, chances are you are going to have to change the batteries out at least once during the life of the device. Most models come with batteries that will last for several days of continual operation, and others come with power saving modes that only activate the device when the wind is blowing. Some also come with convenient indicator lights that will let you know when the battery is running low.
There are several features and functions to consider when you are looking for an anemometer, and some will determine where and how the device can be used. Handheld models that come with protective tops are easier to carry since you don’t have to worry about the digital display being scratched or broken during travel. If you choose a digital anemometer you will want it to come with an easy to read display so you can accurately track the wind speed when it really matters.
Models that come with clearly marked buttons are always appreciated, especially if there are several functions. While inexpensive basic models will often only measure wind speed, you might want to consider paying a little more for a few extra functions. Anemometers that also measure wind chill and temperature are great for hunters, fishermen and other outdoor lovers. Some devices can even be programmed to measure the wind speed in knots, mph, ft/min, along with several others so the information can be easily applied to almost any activity.

The ordinary man on the street may not have use for a refractometer, but a veterinarian, lab technician, gemologist, marine biologist, or even wine grape growers, homebrewers, beekeepers and those who own an aquarium will surely benefit from keeping this type of device handy. This field or laboratory device measures the index of refraction of a sample solution. What distinguishes the best refractometer from a run-of-the-mill device?
A suitable type for your needs
A refractometer can be one of different types. It can be a standard handheld refractometer, a digital handheld refractometer, an Abbe or laboratory refractometer, and an inline process refractometer. For the measurement of the refractive indices of different gases, a Rayleigh refractometer is typically used. There are also automatic refractometers that measure a sample’s refractive index automatically, which is done based on the determination of the critical angle of total reflection.
A traditional or standard handheld refractometer is an analog device that measures the refractive index of a sample liquid. It employs the critical angle principle that governs the way a lens or prism projects a shadow line onto a small reticle made of glass located inside the refractometer. The shadow line is then viewed through a magnifying eyepiece. The sample is placed between the small cover plate and measuring prism. The light channeled through the test sample is either totally reflected internally or passed directly to the reticle. The reading is taken where a shadow line forms between the lighted and dark area and crosses the scale. You will want a handheld model to have automatic temperature compensation because refractive index is highly temperature dependent.
A digital handheld refractometer operates like a traditional handheld one by utilizing the critical angle principle. The difference lies in the way a LED light source focuses light on a prism component or the underside instead of being channeled through a reticle or being totally internally reflected.
A digital handheld refractometer may be more precise than a traditional handheld model but may be less precise compared to a benchtop unit. A relatively large quantity of sample solution may also be required because it will not be spread thinly against the refractometer prism. Various units of measurement may be used to display the result and they include Brix, concentration, boiling point, Plato units or specific gravity, freezing point and others. The refractometer that a brewer would use is the same type that a fruit grower also uses to measure the concentration of sugar in their harvest to see if the fruits are ripe enough. This is called a Brix refractometer, and it measures 0 to 30 Brix or 1.000 to 1.120 specific gravity, which is a very useful range for home brewing purposes. For just such a purpose, steer clear of models containing electronic components or that measure battery acid or some other chemical substance. Refractometers that measure battery acid or other chemical solutions will require the use of available equations for conversion to Brix, aside from likely measuring the incorrect range of refractive indices. Brix refractometers measure the concentration of sucrose in a water and sucrose mixture to find the index of refraction of the sample being tested. Refractometers in the automobile maintenance industry measure the concentration of coolant and the pH value of the coolant oils used in the CNC machining process. Most models come with a sample well made of metal, which is positioned around the prism so it will be easy to clean off a sticky sample such as honey.
An Abbe refractometer is a benchtop instrument that offers high-precision measurement of the index of refraction. The liquid sample is placed into a thin layer sandwiched between a refracting and an illuminating prism. Projected through the illuminating prism is the light source, and a detector mounted on the refracting prism back side shows a dark and light region.
An inline process refractometer is geared for the continuous measurement of a fluid flowing inside a tank or through a pipe. This type of instrument comprises a sensor mounted inline with the flow of fluid and connected to a control box, which typically provides a digital readout along with relay outputs for controlling valves and pumps and 4-20mA analog outputs. The sensor is not placed inline of the process but in a bypass linked by a thin tube.
Useful features for measurement
Automatic Temperature Compensation (ATC) proves to be useful but not a strict necessity if you own a temperature compensation chart. Models that don’t feature ATC will require the temperature compensation to be optically performed and not just as an electronic effect. A good cheap refractometer will still provide an accurate reading despite the absence of ATC since only the instrument’s temperature is important because you will only need a small quantity of sample compared to the mass of the device itself. That being said, premium quality refractometers use ATC as a selling point to enable them to report the same value across a wide range of practical temperatures, generally between 13 and 29 degrees Celsius or 55 and 85 degrees Fahrenheit. ATC becomes a worthy feature to have in your device as a couple of drops of even boiling wort can cool quickly to within that range, giving all-grain brewers a specific advantage for monitoring the runoff gravity typically around 170 degrees Fahrenheit. ATC enables you to use the reading you obtain.
The best digital refractometer comes with software to avoid reading interferences due to excessive ambient light. Shading the prism area prevents interference as well. Some models come with dual or multiples scales. They have the capability of inputting a special scale using conversion information that is known. Some digital handheld units are IP65 rated to signify they are water resistant, so you can wash them under running water.
Easy to calibrate and use
Compared to a hygrometer that simply floats in the solution you’re testing, a refractometer is really not as simple to use. The refractometer makes it tricky to calculate the final gravity adjustment. It pays to know what you’re getting when you buy a refractometer. You will also need to calibrate the refractometer prior to use. Fortunately, calibrating most refractometers is simply done using a sample of distilled water. Most units also come with a calibration screw or knob that enables setting to zero. This is what you will need to do: adjust the refractometer to zero while distilled water is in it. You may need to make a few tries to succeed in this process. For precise readings, you also need to calibrate the device using a wort sample with known specific gravity.
To test a sample, all you need to do is open the sample plate, ensure it is clean and dry, and add a few drops of the test solution. Close the sample plate, making sure there aren’t any air bubbles, and then hold up the instrument against a natural light source. It should be easy to read the instrument as well simply by reading straight from the sight scale, with the reading most often in percent/degrees Brix or refractive index (RI).
