The best way to care for your pet reptile is to provide an environment that mimics its natural home in the wild.

Since their skin is always dry and cannot retain moisture like other animals, it is important that the humidity of their enclosure be closely monitored and there is no better way to do this than with the best reptile hygrometer.

Humidity is the amount of water vapor present in the air. Having the wrong humidity in your pet’s enclosure can lead to many health problems and that is why maintaining the right amount is very important.

Different reptiles have different humidity needs and so before taking your pet home, it is advisable to do some research and ask for professional guidance so that you can properly take care of your pet.

An enclosure that is too humid can cause skin infections or pneumonia for your pet, and an enclosure with low humidity can lead to dehydration and even death of your pet.

So you need to keep track and try to maintain the right amount of water vapor in the air.

Maintaining Proper Humidity using Reptile Hygrometer

To ensure that you have a healthy pet, all aspects of its life must be taken seriously and proper considerations made.

Too much humidity or too little could cause your pet reptile to suffer from respiratory problems, shedding issues, skin disorders, and shell disorders.

That is why you need to monitor the enclosure with a good reptile hygrometer and maintain the humidity level within acceptable limits.

Here are some ways in which you can improve the humidity of your pet reptile’s enclosure and keep it healthy and comfortable;


Substrates can help reduce the rate at which moisture dries off from the enclosure thereby helping to keep the place humid.

Care should, however, be taken while choosing a substrate as some are harmful to your pet.

Substrates like coconut fiber are good for use with tortoise but can cause eye irritation for Chinese water dragons so do good research before making a choice.

You can choose to go with a dry substrate or an absorbent one depending on the needs of your pet reptile.


The design of your pet’s enclosure can also help in reducing the rate of moisture loss. Tall and narrow enclosure designs are good with this and depending on the humidity needs of your pet is a good choice to go with.

Using such designs with animals that need less humidity will save you the stress of always misting as they have as much as they need at every given time.

Water Dish

Providing a water dish in your reptile’s enclosure greatly improves the humidity and allows them to have a nice soak when they want to.

Placing the water dish strategically can have the best effect and so if you desire to have more humidity in the enclosure, consider placing it in the warmer part of the enclosure.


Misting is a very effective way to raise the humidity and keep the substrate wet. Not all reptiles have high humidity needs and so this may not be good for yours.

The only way to know is to do research and seek professional help. While animals like tortoises and Chinese water dragons stand to benefit a lot from this, others like corn snakes could fall sick as a result of the high humidity from misting.

Types of Reptile Hygrometers

There are different types of hygrometers in the market, and each has its own principle of operation.

1. Analog Hygrometer

Analog hygrometers make use of a spring that tightens or loosens depending on the level of humidity. All you have to do is tune them regularly.

2. Digital Hygrometer

A digital hygrometer makes use of non-moving electric sensors to measure the level of humidity in your pet’s enclosure. The readings you get are a result of the resistance due to the moisture present. These types of hygrometers require good maintenance.

3. Chemical Hygrometer

Chemical hygrometers make use of chemicals to show both the cumulative temperature and humidity.
