Buyer’s Guide

What is the Reptile Hygrometer?

The Reptile Hygrometer is an instrument that measures the humidity of a room.
It shows how much moisture in water vapor is present in the air, usually expressed as a percentage. In short, it’s used to measure and monitor relative levels of indoor or outdoor humidity (conditions).

Since reptile habitats have their own temperature and humidity levels, it’s important to monitor the moisture level in their habitats. Too much humidity can lead to health problems for the reptiles and too little humidity will also have adverse effects.

The hygrometer is usually placed near the basking spot of an animal and at a height between one and two feet above the ground. It should also be placed within three inches away from any light source as this can affect readings (if there are UVB bulbs).

Benefits of using a Reptile Hygrometer

Benefits of using a Reptile Hygrometer
There are many benefits of using a Reptile Hygrometer in your reptile tank. Some of these benefits include:

Maintaining proper humidity levels for your reptiles is essential to their health and well-being. A hygrometer can help you do this accurately. If the humidity level is too low, your reptiles can become dehydrated. If the humidity level is too high, your reptiles can suffer from respiratory problems.

A hygrometer can help you keep track of the humidity levels in your tank and make necessary adjustments as needed. It is also a good tool to use for diagnosing any potential humidity-related problems in your reptile tank.

If your reptile is suffering from dehydration, you can use a hygrometer to monitor its humidity levels and change the conditions in its tank to improve those levels.

A hygrometer can help you keep track of the temperature levels in your tank. This is important because different species prefer different temperatures, and keeping them at their preferred temperatures improves their health and well-being.

The reptile will be able to regulate its body temperature more easily with a proper humidity level. Reptiles need high humidity when they are shedding their skin. Reptiles with low humidity levels may become restless and can even stop eating.

The benefits of using a hygrometer in your reptile tank are many, making it an essential piece of equipment for any reptile owner. Make sure to get one that is specifically designed for reptiles, as they will be more accurate than general-purpose hygrometers.

Things to Look Out for in A Good Reptile Hygrometer

Things to Look Out for in A Good Reptile Hygrometer
Reptile hygrometers are important for reptile owners to have in order to monitor the humidity levels in their tanks. There are many things to look for when purchasing a hygrometer for your reptile tank.


The first thing to consider is accuracy. It is important because there is no point in purchasing a hygrometer that doesn’t give you the correct reading. If a device isn’t accurate it could lead to incorrect humidity and temperature readings which will then have adverse effects on your reptile’s health.

If you are unsure of whether or not your current hygrometers’ accuracy is, purchase another one (or two) and compare them side by side. If they are off, replace them!

One of the things to look out for when purchasing a hygrometer is whether or not it contains calibration instructions. Some devices have the instructions printed on their packaging meaning that you can easily check if your device is calibrated correctly before purchase. Other devices will require you to purchase refills of calibration solutions and instructions separately – so be sure to check if this is the case before you buy!

“Accuracy” matters because a person has no use for incorrect readings. If accuracy is poor, it’s likely that reports will not match reality, which can prove dangerous in some cases. If humidity levels are maintained inaccurately, this could lead to health risks for the inhabitants of the space – reptiles included.

A number of factors can affect accuracy, such as wear and tear on certain parts or components, temperature changes, and even the placement of the hygrometer. Some devices are more accurate than others, so it’s important to do some research before settling on a purchase.

If you are still unsure of the accuracy, compare the readings on your hygrometer with another device – if they match or differ by less than two percent, then this should be sufficient for most environments. If not, it may be best that you replace them!

Digital or Analog

The second step is to choose the type of hygrometer for your reptile enclosure. Digital or Analog?

Sensors (analog) hygrometers are typically used in high humidity areas like greenhouses and terrariums, as well as aquariums. These sensors turn on when the relative humidity reaches a pre-set point and then turn off after it falls below that point. This is the least expensive and most common type of hygrometer.

In addition, analog hygrometers come in two types:

  • The first type has a metal plate that expands and contracts with the humidity. This movement is transferred to a needle, which turns on when the relative humidity rises above or falls below your pre-set point.
  • The second type is a non-electronic type that reacts to the surrounding humidity. An example of this type is an analog thermometer with numbers instead of mercury.

The drawback of analog hygrometers is that they can be slow to respond. They also need regular maintenance, such as cleaning and recalibration

Digital Hygrometers are powered by a battery or AC adapter. They have a digital read-out which makes it easy to see the current humidity level in your reptile enclosure. Digital hygrometers are very accurate and respond quickly to fluctuations in humidity. These hygrometers are commonly used in reptile cages and enclosures.

Digital hygrometers operate by a press-button membrane that when depressed, sends a signal to the microprocessor or circuit board. The hygrometer will then either beep loudly and/or flashlights to alert the owner of a problem, or will start recording data that can be retrieved later.

Digital hygrometers provide much more information than analog hygrometers. For example, a humidity readout in percentage (%) or relative humidity (RH), or both. The temperature in the reptile enclosure can also be displayed on some digital hygrometers

Which type of hygrometer should you choose for your reptile enclosure? That depends on how important accuracy is to you and whether you are comfortably calibrating a digital unit. If accuracy is key, then go with a digital unit. If you don’t mind giving it a quick calibration check from time to time, then go with an analog unit.

Digital hygrometers are more expensive than analog units but they last longer and provide accurate readings.


Things to Look Out for in A Good Reptile Hygrometer
The third factor you need to consider when choosing a reptile hygrometer is the material. It is important because not all materials are reliable.

The material also matters because you have to make sure that your reptile hygrometer can resist the conditions of where it will be placed. You need a hygrometer that is designed to resist heat and humidity.

The most common materials are metal, plastic, wood, and glass.

  • Metal hygrometers tend to be the most reliable because they are less likely to be affected by humidity levels. Moreover, they are easier to read since the digital numbers can be seen clearly. However, they can also be more expensive than other materials.
  • If you decide to use a plastic hygrometer, make sure that it is made of high-quality materials and has a protective cover for its sensor area. This will protect you from damage caused by direct contact with humidity in your reptile’s habitat. They are also more affordable than metal hygrometers.
  • Wooden hygrometers are not as durable and reliable compared to metal ones. They can’t really be used for indoor or outdoor cages since they are not water-resistant. However, they are the most affordable option and some people find them more appealing to look at than other materials. Moreover, they are very easy to clean.
  • Glass hygrometers are the most fragile option, but they also tend to be the most accurate. This is because glass does not react to humidity levels as plastic or metal does. Moreover, they are easy to read. However, you will need to be careful not to damage them as they can be quite fragile.

Choose a material that is best suited to your needs.

Ease of use

The next thing to look for is ease of use. You will be using your hygrometer throughout the day, so it should not cause you any additional stress or frustration.

It is also important because you will be able to use your hygrometer for longer if it is easy to work with.

The digital ones are obviously the easiest to use, but many people prefer analog models as well. The main thing here is that you can tell the humidity level at a glance and do not have to spend time looking for information on it – although all hygrometers come with an instruction leaflet anyway which explains how they work, what they are, and how to use them.

Ease of use also depends on the design of the hygrometer. Some models have a backlit display and are easy to read, while others can be hard if you cannot find your glasses or just do not feel like getting up – these will then require some squinting for too long which is not good either because it strains the eyes.

A hygrometer should not be difficult or annoying to calibrate either – you do that when the seasons change. And if it can measure both temperature and humidity with a single device then so much the better!

Ease of maintenance is also important for any hygrometer. If you have to clean it and maintain it with oil or something then that is not a good thing, because who has time for all of this when they are busy taking care of their pets?

The ideal device can be left alone in the terrarium without much interference from its owner – which means less stress all around! You should be able to focus on the health of your reptile and not have to worry about anything else.


Reptiles are interesting creatures that require specialized care if you want them to live healthy and happy life. In order to provide this care, it is important that you have the right equipment, and a good and durable reptile hygrometer is one of the most essential pieces of gear.

One of the most important traits of a good reptile hygrometer is durability. You want your hygrometer to last as long as possible without breaking down or malfunctioning so that you can get the most accurate readings at all times. Because reptiles are often strong and forceful animals who could potentially break things in their cages if they have an issue with something like this, it’s best to have a device that can withstand a lot of abuse.

You should look for hygrometers made from strong and durable materials like metal or thick glass so you know your reptile hygrometer will last as long as possible without being damaged by the animal in its cage.

Durability also depends on the setting and conditions of the reptile thermometer. If you are going to be placing your hygrometer in a very hot place or subjecting it to other harsh elements, then I would advise that you invest in something more durable than if you will just have it sitting on a desktop near an air vent all day long.

If there is one thing I want my readers to get out of this blog, it is that they should always consider the durability of a hygrometer. I would rather have one reptile hygrometers that can last me several years than five cheap ones in the same amount of time because every year or so you will need to replace them and there’s nothing more annoying than having your readings thrown off because your equipment is constantly breaking.

Durability should be one of the top priorities when looking for a good reptile hygrometer, as it will save you time and hassle in the long run.


Things to Look Out for in A Good Reptile Hygrometer2
The next factor we are going to discuss is adjustability. It means that the hygrometer needs to have an adjustable sensing range. There should be a minimum and maximum limit for humidity reading that can be adjusted by you using the device’s controls, or it has enough adjustability if there is no separate knob.

You may have the best hygrometer out there, but if it can’t be adjusted accordingly then that’s not what you wanted for in the first place. The point of a hygrometer is to measure humidity and temperature accurately so that your reptiles stay healthy at all times.

Adjustable hygrometers are more complex and expensive than the ones that aren’t. But, they’re worth it because you can set them to whatever humidity level your reptile needs in order for them to live a healthier life.

Many of these devices show actual temperature readings as well, so even though they are not fully functional as a thermostat, you can get an idea of the temperature in the room. This is important to reptile owners because different reptiles have different temperature requirements.

If you’re looking for a hygrometer to keep an eye on the humidity levels in your home, then you’ll want one that is adjustable so that it can be tailored to the environment. On the other hand, if you have a specific reptile that needs a certain humidity level to thrive, then you’ll need an adjustable hygrometer for their needs.

Remember, it’s important to get the right hygrometer for your needs, so make sure you can adjust the readings before making a purchase.


Here are some tips to consider before purchasing a hygrometer for your reptile:

  • You can use the Hygrometer with or without batteries. If you choose not to have any batteries, then there will be no need of changing them over time. However, if it is used frequently and stays on all the time, then it might require battery replacement at some point.
  • There are many brands on the market that manufacture reptile hygrometers, however; it is important to choose one which will be able to meet your needs and requirements.
  • You must ensure that you check out for specifications of the device before purchasing one in order to avoid any issues later on. All products may not perform the same as one another.
  • The Hygrometer can be used for other purposes such as monitoring the humidity levels in your home or office. This is a great investment to make if you are someone who wants to maintain a healthy environment.
  • Reptiles need a specific level of humidity in order to stay healthy and active. If the humidity levels are too high, then it might lead to illness. On the other hand, if they are not sufficient enough, your reptile may be dehydrated and potentially die.
  • If you have a pet snake at home or any type of reptile for that matter; you must ensure that the temperature is within an appropriate range as well. Failure to do so may result in the death of your beloved pet.
  • You can save money by not having to take your pet snake or reptile to the vet often. It is possible that they burn through a great deal of cash when it comes to visits.
  • A good hygrometer for reptiles will cost you around $20. However, it is a great investment to make and can save you money in the long run.
  • When purchasing a hygrometer for your reptile, be sure to get one that is both accurate and reliable. There are many on the market which claim to do both, however; not all of them meet the mark. Do your research before purchasing to ensure that you are getting a quality product.


Where do you put the hygrometer in a terrarium?

The most accurate place to measure humidity for your terrarium is at least two inches away from any surface. Your substrate, glass, or screen top are all good places because they will not skew the reading. It should be placed on something that won’t block airflows such as tinfoil or a piece of paper, but definitely not cardboard. Your humidity gauge can be placed on the screen top if you have it (just make sure to test this and see that it doesn’t skew your readings).

Are reptile hygrometers accurate?

Reptile hygrometers need to be calibrated in order for them to accurately read the humidity levels. This is an easy process, and should only take a few minutes if you are following instructions correctly.

Are cheap hygrometers accurate?

Cheap reptile hygrometers are not very accurate. If you want to ensure that your humidity levels are being measured accurately, then it is best to purchase a good quality product rather than go with the cheaper option.

Are digital hygrometers better?

Digital hygrometers can be easier for some people because of how easy they are to read, but analog hygrometers can be just as good if you take the time to calibrate them correctly.
