Whether you are looking for the best hygrometer for reptiles or indoor use, you have come to the right place. Following weeks of extensive research, we have come up with a guide that can help you in finding the right model for your specific needs. Read on to learn how to make an informed decision.
What type are you looking for?
There are roughly two kinds of hygrometers you can select from the plethora available for sale these days. Some are made to serve just one purpose while others are designed to be thermo-hygrometers. What this means for you is that these devices can measure out both the humidity and the temperature of the room you place them in.
Of course, opting for a 2-in-1 alternative is always tempting, and that’s because you will be able to make the most of it. In our experience, however, those devices made to fulfill your every wish and desire will most likely fail to do so.
Therefore, if the product promises to tell you the time, measure the temperature, offer you readings pertaining to the humidity of your environment, and even the barometric pressure, you might as well steer clear of it.
What is a hygrometer used for?
In the end, it all comes down to the purpose you are trying to achieve. Some of the best hygrometer reviews might tell you that you require one to make sure that your home never becomes the victim of mold, and we aren’t here to disagree.
In fact, keeping track of the relative humidity in your home is a good idea at all times as it can assist you in feeling comfortable at all times. Some of our team members have a hard time dealing with high temperatures and high humidity levels, for instance, and both of these combined might make them experience a whole deal of symptoms one of which is their heart racing.
If you are known to suffer from any allergy or breathing-related health issue, you need to make sure that your home is not affected by mold. It can damage both your body and your furnishings, not that the latter matter all that much when compared to your personal health.
The fact is that owning and using a hygrometer on a regular basis can let you know how you can set your thermostat in such a way so as to prevent these mishaps from ever occurring.
Data logging & readings
If you’ve gone away from home for eight hours, for instance, you virtually have no way of keeping tabs on your indoor humidity, that is unless you own a device that can tell you the maximum and minimum levels that it has detected. Since not all hygrometers are made the same, they do not come with the same universal features and functionalities.
For your sake and that of your family, we urge you to get a model that can tell you the lowest and highest levels that have been recorded. In case you know that you have trouble with your breathing or heart, this feature can make all the difference when it comes to saving your life.
What applications do you have in mind for your hygrometer?
The best hygrometer is the one you use for the right application, given its features and characteristics. While it may seem that all the hygrometers you can find on the market do the same thing, which is to gauge the humidity range, that doesn’t cover, by far, what hygrometers are used for, and how they can help you. To get the best hygrometer, consider the following applications and how they may influence your decision to purchase one model or another.
– A hygrometer to use at home
There is nothing more straightforward than a model that’s dealing with measuring humidity in your home. However, you should know that you don’t have to opt for a model with outstanding precision, as you would do when shopping for a model that would be a good fit for your humidor. There are, of course, several factors to consider, such as where you want the hygrometer to be installed, or if you need to monitor more than one room.
Real-time alerts could be one thing for which a digital hygrometer will be handy to have around. If you need to monitor specific areas, such as an attic, you will want to know if the conditions change and can affect the conditions in your home. For such a purpose, remote sensors are a must.
– A model for your humidor
Without a doubt, the best hygrometer for a humidor must prove excellent in all aspects, with accuracy on the top of the list. Your cigars need proper humidity range if you want them to keep their flavor. That is why hygrometers for this particular purpose are in a league of their own. You will have to purchase a highly accurate hygrometer, and the type you usually use for your home will not cut it.
Here is a little secret that you might not be aware of. Some manufacturers equip their humidors with poor quality hygrometers to keep the costs down, which is why you should consider investing in such a device separately.
A model with a magnetic mount would be great. You must find a place for your hygrometer inside the humidor, which is why such aspects are essential. A wireless hygrometer that can be monitored from a remote location could be a sound investment for your humidor.
– Ideal for your terrarium
As a reptile owner, you are most probably most aware that these pets need particular conditions to thrive, and a specific humidity level is a must. That is why it is highly recommended that you purchase a hygrometer for your terrarium. Before installing it, make sure that you understand what conditions are necessary for your reptilian pet to live a healthy life inside your home.
With those answers, you will be able to pick the right model. Ideally, you should get one that also indicates the temperature inside the terrarium for the simple reason that reptiles can be quite particular when it comes to such conditions. Two digital hygrometers might be needed if your reptile prefers some spots for their cool temperatures and others when it wants to get a bit warm.
– An outdoor hygrometer
While outdoor devices that are used for gauging the weather conditions are rarely just hygrometers, it is worth talking a little about them. They are usually weather stations, and it’s not unusual for some manufacturers to incorporate the best hygrometer they can in their products. With the help of weather stations, you can understand more complex details about the ambient weather outside, including the humidity levels.
These stations come with remote sensors that can be installed outside, while the main display and unit are placed inside so that you can know, at a glance, what awaits you when you decide to walk out the front door. Such details can be quite important if you need to know whether you should better get your umbrella, or the ambient weather is more likely to remain dry and calm.
– The perfect hygrometer for your greenhouse
Another area of your property where you might decide that a digital hygrometer would be great to have is a greenhouse. Here, the plants you grow can thrive, but only if certain conditions are met. Water vapor conditions are just one of the details that create the intricate environment of a greenhouse. When you step inside it, you might notice that there is a lot of humidity.
However, you can’t tell whether it’s inside the favorable range for your plants to grow without some digital hygrometers to say to you precisely what you need to know. For this reason, you should invest in these devices and place them strategically inside your greenhouse. You must also bear in mind that the conditions inside the greenhouse should never change dramatically as plants can be quite sensitive.
– For your musical instrument
Musical instruments are demanding when it comes to care and maintenance. The wood used for violins, guitars, and not only is prone to various mishaps when the humidity levels increase or decrease significantly. Your musical instrument can become warped, or even crack, and that means that it will become pretty much useless.
For this reason, it’s a good idea to have a humidity sensor inside the case where you usually keep your instrument. While it may appear that keeping your instrument inside its case protects it from all such unpleasant consequences, you should be extra careful, especially with costly models. Be safe rather than sorry, and invest in the best hygrometer you can find for an instrument case.
How to know if the hygrometer you want to buy is accurate enough
Another aspect that you should never overlook when you go shopping for a hygrometer is accuracy. However, you may find yourself overwhelmed by the large number of hygrometers available that are advertised as being extremely accurate. As a rule of thumb, you should be aware of the fact that cheaper models usually have less accuracy than more expensive hygrometers.
The ±% RH rating is what should concern you, and most manufacturers will disclose this information in the description of the specifications for each model they sell. This number tells you what error margin the device operates on. This error margin can vary from 1% to 4%, so there can be quite a difference between the various models you will see when you go shopping for this type of device.
It all boils down, once more, to the application you intend to use the device for. If you only need some general information on the conditions in your home, an inexpensive model should do the trick. However, if you intend to use the respective device for controlling the humidity levels inside your humidor or for keeping your musical instrument in pristine condition, you should invest in a costlier hygrometer.

Frequently asked questions
Q: What is a hygrometer?
How much water vapor exists in the environment is an essential detail that can help you make decisions regarding how you should modify the conditions in the respective environment. To do that, what you need is a hygrometer, which is an instrument for measuring humidity that is easy to use.
There are various types available, so don’t be surprised to find a wireless hygrometer that can be connected with your phone via an app. With its help, you can determine the humidity levels inside or outside, depending on what you have in mind.
It would be safe to say that a hygrometer is nothing else but a humidity meter, as that’s precisely what it does. It measures the humidity levels in the air, and that can give you some essential information you can use later for adapting the conditions so that they meet the required criteria for the application you have in mind.
Q: How does a hygrometer work?
A hygrometer uses particular materials that attract moisture, and then calculate the humidity levels by combining data extracted from how the materials modify as moisture is absorbed. Although old models of hygrometers used a hair taken from the tail of a horse or even human hairs, modern hygrometers no longer depend on such things to monitor humidity.
The most common configuration is one that works with two bulbs, one wet and one dry. As the temperature around the hygrometer influences the two bulbs, humidity is calculated as follows: moisture evaporates from the wet bulb, and that causes the temperature calculated to drop.
A hygrometer will establish the difference in temperature between the wet bulb and the dry bulb, and the result will be the relative humidity present around the hygrometer at any moment. This is how digital models work nowadays, and the old model that used human or animal hair has been out of fashion for a long time.
Q: Are hygrometers accurate?
If you decide to purchase a hygrometer, the most important thing you will want to know is whether the device can deliver accurate readings or not. That means that you will have to know a little about the ±% RH rating and what it stands for.
RH, as you may well know it, is the abbreviation for relative humidity, and this rating refers to the error margin a hygrometer can present. It doesn’t matter if the model you want to use works with remote sensors or not. This rating is what you should be aware of so that you can tell whether the hygrometer you picked is accurate enough for what you have in mind.
Its accuracy can vary up and down, and the most inexpensive models can have an error margin of up to 4%. Those that are considered highly accurate have a rating of ±1%, so that’s something you should pay attention to when you examine various models.
Q: Where are hygrometers used?
There are plenty of applications for hygrometers, as you may well know. They can be part of weather stations that gauge the overall ambient weather conditions so that you know what you can expect when you walk outside. These units usually come equipped with an accurate hygrometer so that they can even predict if there is a high chance of rain.
Of course, an indoor humidity monitor is the most common application you can find for such a device. Since the living conditions can be affected by humidity, it serves to know such details. A digital hygrometer is quite a common thing in many modern homes.
Hygrometers can be used in many different ways. They can measure the humidity levels inside a terrarium, or gauge the conditions inside a cigar humidor. People who play musical instruments may also use them to protect their violins or guitars. You will also find hygrometers in greenhouses.
Q: Who invented the hygrometer?
The hygrometer, as we know it today, is a far cry from the first units that were worthy of such a name. In the 1400s, Leonardo da Vinci was the first to come up with the concept of a hygrometer. However, the model he created was very basic, and it would take more than two centuries for Francesco Folli to make a more usable hygrometer.
However, Folli’s hygrometer from 1664 was not yet accurate enough to offer reliable information. Horace Bénédict de Saussure is considered the real father of the hygrometer as he made the first model to work with human hair to measure humidity in 1783. All these models were mechanical.
John Frederic Daniell also advanced the science of this device as he created, in 1820, the first dew-point hygrometer. His invention was capable of establishing the point at which the air became saturated with humidity.
The humidity level in your home is very important for your comfort and for your house. Get yourself a hygrometer to measure humidity, and then you can determine your needs and choose from an extensive array of tools for controlling household humidity.
Low humidity – effects on your health and home
If you’ve got an irritated throat and nose, and your skin is permanently dry and lips chapped, it can mean there isn’t enough humidity in your home.
Your house doesn’t react well to low humidity, either — the dust builds up, the furniture’s joints will get loose and the floors and stairs become squeaky.
High humidity – effects on your health and home
On the contrary, high humidity makes you feel sticky and it gives you allergic reactions, like sneezing and chronic coughing.
Also, your house might develop mold on the walls and the ceiling and you might struggle with insect infestations.
Checking your household humidity
An instrument called hygrometer is of great help because it measures the amount of moisture in the air. There is more than one type of hygrometer — you can opt for a mechanical one or an electronic one. The best place to leave your hygrometer is a living area away from the kitchen or the bathroom as there is a lot of humidity there.
For your comfort and for your household’s sake, the relative humidity levels should be between 30% and 50%. During the summer, 55% is acceptable. However, if the humidity level is anywhere under 30% or over 60%, you will feel uncomfortable and it could be damaging to your home.
How to deal with low humidity
Dry air in your house has a chilling effect because it increases the cooling power of perspiration. Once you manage to get your indoor humidity at the right level, you can decrease the thermostat temperature by a few degrees and feel just as warm and comfortable. Your heating system’s efficiency will increase by 1% for every degree you dial down and that means considerable savings during the winter.
You can start increasing your household humidity by adding a house humidifier to your heating system.
This type of humidifier comes with a built-in humidistat which automatically prompts the unit to produce the perfect amount of moisture. Some of these systems include an outdoor sensor that takes into account the air temperature. Your best bet in terms of efficiency are steam versions.
You can also weatherproof your doors and windows and by doing this you’ll remove air leaks that allow humid air to escape. You can check how well you’ve insulated your home using an insulation multimeter. Or, if you don’t want to do any of that, you can just purchase a portable humidifier.
How to deal with too much humidity
During the summer, you can keep your house humidity under control using the air conditioning unit. Air conditioning helps to remove excess water as it cools the air inside your home.
This doesn’t really work for homes that have basements or are located in coastal regions and in this case you may encounter high humidity problems year round.
There are a few solutions to this problem: you can buy a portable dehumidifier in case you struggle with isolated dampness in your household. Or you could purchase a vent fan for your bathroom.
A more efficient solution is to install a dehumidifier in your heating, ventilation and air conditioning (HVAC) system. It is equipped with automatic sensors which will detect the humidity level in the air and will adjust it accordingly.
As a pre-emptive measure, you should make sure excess moisture from the outside isn’t allowed to get inside your home. Pay attention to the gutters and drain pipes and repair any leaks you find. Use drain pipes extenders to keep water away from the foundation and make sure all your window wells are covered so they don’t accumulate water from the rain.
What about new constructions?
New houses built in high humidity areas are especially prone to excess interior humidity because they’re built tightly and air leaks are rare. Not having air leaks is efficient, but it can contribute to an increase in humidity level inside the house.
To prevent that, you can add a heat recovery ventilator (HRV) to your HVAC system — it removes moisture without losing any heat.
Indoor Humidity Temperature Monitor
If you have been looking for an indoor hygrometer that doesn’t cost too much and is rather user-friendly, you might have just encountered it. This model is a winner when it comes to usability, and you don’t even have to take our word for it as there are dozens of reviews attesting it.
