These devices are extremely important so make sure you only purchase products that offer accuracy and efficiency. In the case of body temperature readings, stay away from mercury glass thermometers that can break easily and release mercury which is extremely toxic.

Frequently asked questions about thermometers
Which thermometer is used for animals?
Just like humans, animals need to have their body temperature tested in order to check whether they have a fever or not. There are three ways to do the readings, and those are rectal, axillary, and in the ear.
While the rectal thermometer is considered the most accurate device for measuring the internal core body temperature of pets, the other two are correct as well. For the rectum and the under the armpit area it is advisable to use a digital thermometer. As for the ear, you should use an infrared tool that is safe and doesn’t require much time to determine a correct temperature reading.
Which thermometer is most accurate for babies?
Choosing the perfect thermometers for babies is quite an important things, as most parents are probably aware. Not all of these measuring tools are safe for babies so make sure that the age of the baby corresponds.
For instance, the best way to get an accurate reading for an infant, especially those who have less than three months, is to use a rectal digital thermometer. Once the baby gets past 6 months, you can easily start to check the body’s temperature with an ear thermometer.As far as forehead infrared thermometers, they are a good way to see if the baby has a fever when he or she reaches three months old.
Who invented the thermometer?
Before the invention of the thermometer, there was a device called thermoscope that showed only the differences in temperatures. Galileo Galilei was the one that crafted this idea. At the beginning of the 17th century, an Italian Inventor called Santorio Santorio made the first baby steps to what we use today. He was able to put a numeric scale on his thermoscope. But none of these inventions were precise tools to check the temperature until Daniel Gabriel Fahrenheit made a discovery and came up with the mercury thermometer which was used until recent years. The standard temperature scale was named after him and used the principle of dividing the freezing and the boiling points of water into degrees.
What thermometer do doctors use?
Depending on the age of the patient, doctors use the same type of thermometers that are recommended for common use for adults and babies alike. While for infants it is preferred to measure the body temperature using a rectal thermometer, for toddlers and adults doctors use digital thermometers placed orally or axillary.
Given the fact that forehead infrared thermometers are non-invasive and don’t require any contact with the patient, many specialists recommend them for everyday use. Some models that are found in the medical and health service are multi use, meaning that they are suitable for reading the temperature in more than one area of the body.
Are mercury thermometers dangerous?
Thermometers that work with mercury have a small silvery ball inside that can cause a lot of harm if the glass breaks. Once the mercury is released, it will evaporate and contaminate the surroundings. It is toxic not only to nature and fish but for humans as well. Moreover, it is a potential threat especially for pregnant women and young children.
Each thermometer contains about 1.5 grams of mercury, more or less. You should be aware that in order to contaminate 20 acres of lake, you need only 1 gram of this toxic substance. Therefore, it is advisable to avoid this type of thermometers and opt for safer ones, such as digital or laser.
Where does a meat thermometer go in a chicken or turkey?
Meat and poultry need to be cooked at a certain temperature to become juicy. Otherwise, you’ll end up serving a try and tough food if you cook it too much. You can avoid this issue if you opt for a meat thermometer that allows you to get the poultry done in a perfect manner.
A good advice is to use the thermometer at the end of the cooking time and ensure the probes remain in the meat for only 15 seconds, at a depth of 2 inches or to the indicator mark featured on the device. If you want to serve a delicious whole poultry, make sure to insert the unit into the inner thigh area near the breast, without touching the bone.
Which thermometer measures the temperature of the air?
In order to measure the air temperature, we can use four different types of thermometers. The first one is the liquid-in-glass thermometer or bulb that are made of a glass tube with a round chamber at one of its ends. When the temperature changes, the volume of liquid either expands or contracts. The second device is the bimetallic or spring thermometer that you can mount on a house, barn or backyard. Thermoelectric thermometers are digital tools that use an electronic sensor to generate electric voltage. As the electric current travels and the electrical resistance changes so does the temperature. Last, the infrared ones can measure the temperature from distance thanks to the infrared laser technology.
What thermometer should you use for ovulation?
Women that want to conceive a baby must take their basal body temperature over the course of their menstrual cycle. To get accurate readings, they should use a basal digital thermometer that detects the temperature shift before ovulation and offers interpretations of their measuring data for accurate fertility predictions. Most of these devices are easy to use and come with Bluetooth functions so women can sync them with their smartphones. This way, they have all the important information stored in one place. Moreover, basal thermometers feature reminder alarms that ensure there’s a consistent timing of the temperature readings and automatic display of the cycle days.
Why are some thermometers made of glass?
The reason why some thermometers are made of glass has to do with the low coefficient of thermal expansion. Because thermometers are exposed to large arrays of temperatures, it needs a material that doesn’t change its dimension in order to provide accurate readings. If it weren’t for glass, the thermometer would expand unevenly and cause irregularities and faulty readings.
Also, given the light bulbs, the glass transparency is more suitable for temperature measurements. Moreover, the glass can be easily cleaned thanks to its waterproof features. The material is able to withstand a high level of temperature without being broken.
When should a thermometer be calibrated?
Digital thermometers require calibration if you want to be sure that the temperature readings are correct. Whether you use the device for cooking, for measuring the body’s temperature or for atmospheric purposes, you should calibrate it from time to time.
Before you attempt to use a new tool, it is advisable to proceed to a calibration in order to check if the thermometer works as it supposed to. If you accidentally drop the thermometer, you should know that another calibration is mandatory. When exposed to extreme temperatures, these devices tend to be affected, and the readings are faulty. Calibrating the thermometer is imposed if you use it on a daily basis.
Are temporal thermometers accurate?
