Questions & Answers

7 Customer Questions


I have a leopard gecko where in the tank do I place this.. hot side or cold?

Answer by ChewyJul 19, 2018
Leopard Geckos practice "thermoregulation," meaning that they will move into hotter or cooler areas to raise or lower their body temperature as needed. The terrarium should consist of several different temperature gradients, and there should be at least one hide in each gradient. The thermometer would need to be placed inside the tank to accurately measure the temperature.

Is this water proof?

Answer by ChewyOct 15, 2021
The Analog dual thermometer and humidity gauge is not waterproof. It should not be used in aquatic environments or if set up in a terrarium it should not be misted directly with water.

Does it need to be plug in?

Answer by ChewyDec 29, 2022
This thermometer and humidity gauge does not use batteries or outlets, so it can be used straight out of the package.

Can I use this to stop my tank from going over a certain temperature? Like will it turn off my heat pad if it gets too hot?

Answer by ChewyFeb 13, 2019
Designed to be easy to see and use, it lets you precisely monitor the temperature and humidity of your terrarium, all in one place. It won't turn off automatically.

Decent price for ease of mind

Seems to be working really well - as designed. Sporadically checking it against digital and laser thermometers and matching perfectly.
