Owning reptiles isn’t as easy as it might sound — these little creatures need a lot to ensure they survive. The right tank, the right food and the right temperature all contribute to their well-being, but what about the right humidity? Animals such as bearded dragons, leopard geckos, iguanas, corn snakes, chameleons, tortoise and turtles all require a specific humidity to thrive.
To ensure the correct humidity is maintained, you will need to purchase a hygrometer. These devices accurately show you what the humidity level is inside the vivarium and some even allow you to adjust it to the correct level. This is very important, especially if you live in an area where the weather is constantly changing and your tank may be susceptible to temperature changes.
However, how do you know which one to buy? What are you looking for? And how do you know if it’s accurate? Fortunately for you, we have compiled a buying guide below giving you all the information you need on the best reptile hygrometers, including factors to consider.

Why You Need A Reptile Hygrometer
Reptiles are ectotherms, which is the scientific word for cold-blooded. This means that they rely on sources of heat and humidity that are outside of their own body to keep them warm and to maintain the correct body temperature and moisture levels. In the wild, this would be in the form of natural elements, but, when kept as a pet, it is up to you as their carer to provide them with the correct levels of humidity and temperature.
If your reptile isn’t kept at the right temperature and doesn’t have the right humidity and moisture levels, it can have an impact on their health, particularly on their digestive and immune system.
There are many ways to regulate humidity for your reptile or amphibian. These include misters, waterfalls, drip systems, humidifiers, dehumidifiers, foggers, water bowls, spray bottles and live plants. The type of reptile you have will, of course, determine how much humidity you need in the tank.
A hygrometer helps you to keep on top of the humidity levels of your vivarium, so you can keep the reptile enclosure at the set humidity. As the temperature outside your reptile’s home changes, you may need to change the temperature and humidity inside, too.
What To Look For In The Best Reptile Hygrometers
There are a few things to look for in the best reptile hygrometer so you can be sure you are getting the right one for your reptile and vivarium.
Digital or Analog
There are two main types of reptile hygrometer: digital and analog. Digital hygrometers have sensors, including remote sensing probes and a display unit. They are very accurate and durable and are not very expensive. The downside is that they can have technological glitches and need a power source, such as batteries.
Analog hygrometers do not have the issue of technological glitches like digital ones and a very easy to use. The downside is that they are not as accurate and need calibrating every now and again. They also need to be replaced every now and again.
Display
Most hygrometers come with an LCD display. This means they are easy to use and read and will make life much simpler for you.
Accuracy
Of course, you want your reptile hygrometer to be accurate, otherwise it won’t be very useful! Some hygrometers can have huge error margins, which can be very dangerous for your reptile. Always ensure you are buying from a reputable manufacturer that will provide you with an accurate reading.
Durability
Hygrometers don’t always last long, so again it is important to ensure you are buying from a reputable manufacturer that will provide you with a durable device so you don’t need to replace it very often. It is also worth looking for a hygrometer with warranty, in case you purchase one that breaks easily.
Extra Features
Some hygrometers are also thermostats and thermometers, which can be very useful, especially if you have more than one reptile tank. This way, you can read both the temperature levels and the humidity levels at the same time, and easily adjust them together. This also limits the number of wires and appliances you need to have to keep your reptile happy.
Other features of hygrometers that you might want to keep an eye out for are memory settings and ease of setting up. Memory settings are particularly beneficial if the hygrometer loses power, as you do not have to re-set the settings when it powers back on — it simply will have remembered the previous settings for you to use.
Now you know what to look for in a reptile hygrometer, take a look at the best hygrometers we recommend on the market below. These are all available to you on Amazon.
