If your bearded dragon was raised in captivity, a good humidity level in their terrarium is extremely important. The required humidity level should be kept around 35 to 45%. This level of humidity is identical to the wilderness of Australia.

As you know, these reptiles came from dry, semi-desert areas in Australia. They lie under the heat of the sun during the day, and at night they’ll look for a suitable place to hide and sleep. Beardies need heat, but how will you know if their terrarium’s humidity isn’t too high or too low? The answer is by using a thermometer.

How is a Thermometer Used for Bearded Dragons?

Using a thermometer for a bearded dragon’s terrarium has two main functions. First, it is used during the early phase setup to check a good temperature, and so that the heating equipment could be permanently mounted in the terrarium.

And secondly, the thermometers are used to accurately monitor the temperature of the bearded dragon’s environment. This is by mounting the thermometer in one area where the temperature should be monitored. In this way, if there is a sudden increase or decrease of the terrarium’s temperature, it could be immediately be identified and corrected as soon as the change happens.

The Required Level of Temperature for Bearded Dragons

Thermometers are used for bearded dragons to be able to read the right temperature range for beardies. The right amount of heat for bearded dragons should be around 40 degrees Celsius or 104 degrees Fahrenheit, and with a temperature gradient for about 24 to 34 degrees Celsius or 75 to 93 degrees Fahrenheit.

How to Choose a Good Thermometer?

When choosing a thermometer, you should also check out its quality aside from the price. You should choose a good size, make sure that you pick a small one, how reliable it is, its durability, and its design.

Aside from monitoring the terrarium’s temperature, you should also definitely consider the durability of the thermometer. It would be great if it would last for at least 5 years or so, rather than lasting for a year or a few months.

And of course, a good design. If you are thinking about letting your beardie’s thermometer last for a long time, then make sure that the design of the probe would add a good decorative design on the enclosure. You won’t want a thermometer that is looking out of place on the terrarium, so make sure that you buy a good one.

But if using a tank terrarium could not be avoided, then make sure that it is mounted with a thermometer, this way you could always monitor the temperature of your bearded dragon’s terrarium, and immediately adjust it on the required amount of heat.

The Enclosures Ventilation

Aside from using thermometers to check on the terrarium’s temperature, you should also make sure that the enclosure has good ventilation. This is the best way to reduce the humidity level of the enclosure.

Also, because of a good air flow, it will provide your bearded dragon with enough, fresh supply of oxygen making it live more comfortably in its terrarium.

Three Types of Thermometers

There are three types of thermometers available in the market, and these are:

Digital Thermometer

The temperature level will be shown on a little screen in numbers. Thermometers like these could only work when there are batteries in it.

Analog Thermometer

This thermometer is already made with numbers on it that shows the degrees of both Fahrenheit and Celsius. It doesn’t need any batteries.

Chemical Thermometer

Thermometers like these are made with a chemical substance, this is to help indicate the temperature on an accumulative scale. An example of a chemical that is used is Mercury.


Lizards like the bearded dragons, need enough humidity level in their terrariums, and to make sure that the heat coming from the heating equipment isn’t set too high or too low for your beardie’s comfort, you should use a reliable thermometer to always check the temperatures level.

And if you want, you could use two thermometers on your pet’s tank to check the temperature on the heated area of the tank, and as well as the cooled part. If you have used a digital thermometer, then make sure that the wires wouldn’t get chewed by your beardie.
