Zoo Med Hermit Crab Thermometer and Humidity Gauge, Colors May Vary

I have this for my hermit crabs. The thermometer would never read over 68 degrees no matter what I did. I bought an extra heater and raised my house temp with no improvement. The tank felt warmer than my house temp so I bought a different thermometer. It registered 78 degrees on one side of the tank and 71 on the other! This thermometer is VERY inaccurate! Do not buy it! The hydrometer seems to work, but I'll be replacing that portion too just in case!

Poor quality thermometer and humidity gauge. What do you expect for the price? I expect it to at least be close to accurate. I have a digital for about a dollar more that works great. This one is hard to see and inaccurate.

Great concept having a thermometer and humidity gauge in one compact unit. Well made and it works as it says it should! The gauge is small enough not to interfere with the crab habitat. Having the color coding to warn you of too low, normal, or too high conditions is brilliant. Easy enough for my 8 year old to determine the weather conditions in the tank.

These are inexpensive but work well -for awhile anyway. This is the second one I have bought and each time one of the gauges quits working after a couple of months. Secures well to the glass, and the colors on the thermometer make it easy to read at a quick glance.
