The Top-Rated Reptile Thermometer (Recommendations)









Guide For Reptile Thermometer

1. Functions & Features

If you are a total beginner in raising reptiles, the thermometer can sound a bit strange to you.

In case you may not know, it is a device that measures the temperature level inside your pet tank and then shows the result on its screen.

Different kinds of reptiles need a particular optimum temp, so keeping the tank at the most suitable temp is required.

2. Classification

After getting the overview of a thermometer’s functions and features, we would now like to introduce some common types of the device currently available on the market.

From these, you can consider which is the best product for you!

  • Analog Thermometer


The one above utilizes a bimetallic strip. This strip is used to convert a temp change into mechanical displacement.

The analog type can also come with several other techniques, such as the one with liquid in glass (takes advantage of alcohol or mercury expansion), or gas (uses gas pressure).

  • Digital Thermometer

This type of heat checker is different from the analog because of its mechanism.

A digital thermometer for reptiles utilizes sensors, which are either thermistors, resistance temp detectors, or thermocouples.

All of these models can measure the temp changes according to the voltage or the resistant change.

A humidity and heat gauge

They can quickly respond to the temp change and produce a more accurate result than analog ones.

  • Infrared Thermometer

An infrared temp gun (The Serpentarium)

To identify the temperature, the infrared thermometer for reptiles first determine the extents of thermal emissions from the pet’s body.

They feature a lens to focus thermal radiation to their detector, then turn them into electrical signals. 

Next, analog will be converted to a digital signal shown on the screen. Hence, you can easily read the final result.

But there is one thing you need to remember. These heat monitors only work well within a specific distance!  

3. Installation Tips

Where you place this tool should be up to the heater position.

Then you can start to measure the temp inside the tank from the daytime to the nighttime. Below are several tips for you to correctly set up this tool.

The position of the heat checker

If you are using a heating pad, heat mat, or any other contact heaters, you should place this tool on their surface.

By that, you will keep your reptile free from getting burnt.

In case you get a warmer and a colder surface, it is a need to have three heat checkers: At least one for each area and one for the central position.

Once you set thermometers correctly, you have already made a huge step in protecting your adorable little pet.

Also, ensure your pet not to step on them because they will end up in false readings.
