Design and Features

Being a reptile owner means paying close attention to ensure you provide your pet with a comfortable environment where they can remain fit and healthy.

Reptiles are ectotherm, this means they rely on external heat sources to regulate their body temperatures, most rely on the sun combined with rocks and branches that have been baking in the sun.

There are three thermostats in the Exo Terra range, these include the 100W, 300W, and 600W.

The 100W and 300W are basically the same, they provide an on and off function but do not offer the pulse proportion.

The smaller 100W and 300W thermostats are black boxes with LED indicator lights.

This review is focusing on the 600W thermostat from Exo Terra, which is different from the other versions with its pulse proportion and dimming options.

It offers an LED and digital screen and can control heating devices up to 600W.
