Questions & Answers

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.

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.

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.

Not Accurate!!!

I have NO IDEA if this gauge is accurate. Both swing way to inconsistently for my taste and I need for it to be stable. The temperature SHOULD NOT instantly go down, if I turn off the lights at night time NOR if the humidity drops like crazy with spraying only once - twice a day. I am about to get my millipede very soon and I don't want anything to happen to it due to this gadget not working properly. I am about to get a digital hydrometer/thermometer very soon since I DO NOT trust this gauge.

Good product

I like this, I have a few of them. It isn't the most precise thermometer/hydrometer, but it is really good for getting an estimate. For the animals I have all I need is an estimate and this works. A lot better than winging it

handy little gadget

This is a nice size and super nice for a quick glance monitor. I will say that is off about a degree on both the humidity and thermometer. We had a regular mercury one next to it and that one is always spot on - this one was just a bit off.

Not accurate at all

We compared this with other Thermometer including digital and it was way off. It kept telling us the humidity was between 70 and 80 and the others were reading between 15 and 20. And temp was reading between 80 and 85 when the others read 100 to 107. Not even close. Dangerously off. How are you supposed to accurately copy a habitat with this

Alright product

I initially bought two, just so I had one for each corner of my tortoise enclosure and also so I could gauge how accurate they are. They both sat at the same humidity ready sitting out in my room for a week just to make sure they work, and after putting them in the enclosure they did great...up until the month/month and a half mark and ones temperature gauge doesn't work, it's constantly sitting at 90° which isn't accurate, I bought a infrared temp gun and the spot the thermometer sits reads 82°. Also fairly certain the same thermometer that the temperature gauge doesn't work that the hygrometer gauge is going out as well. So all in all I would like to give it 5 stars but the only way I'd recommend it if it's for a temporary situation, or maybe if it's in an enclosure that doesn't have to be so humid. But for me personally it lasted a month and has crapped out on me

No temperature

Very disappointed worked for a few months. Humidity changes but the temperature does not move, stays on 70 all the time

Works well

I haven't had any problems with this. I put it in the snake enclosure and it helps measure the humidity for me. (I also have another thermometer). It can stick to the glass or you can just set it inside.

Does it's job

The first one I got didn't work, but chewy sent another super quickly and didn't charge a dime. So far it's working like it should!

Not a very good gage of Humidity at all... knew I should of gone with Digital. Save yourself the time and money and don't buy this one
