Digital Thermometer and Hygrometer for Reptiles Terrarium pet keeping, Digital Indoor Outdoor Temperature Gauge and Humidity

Had this for 3 years and used it indoors. Calibrated by occasionally taking the unit outside and comparing the reading with the official weather in my area and it seems to be accurate. Today it's raining and it does read 99% humidity. This has been a great value for the money.

This thing works. And it is pretty accurate as long as you position the probes properly. We thought at one point it wasn't working right on the hygrometer side, because the reading were super low, even right after misting our gecko tank. But it ended up being that the probe for humidity, which was placed in a corner, had gotten turned around so that the open grate part was facing the corner. As soon as we placed it differently it was giving correct readings again.

Really easy to set up and use, but I do question its accuracy. The temperature seems accurate but the humidity seems to hangout at 80-100%, which seems less accurate. (In the photo, I had recently watered my plants, hence the mist on the glass). I knocked one star off of easy to use because mine came with a defective suction cup. It’s a lil malformed and won’t stick to anything.

python like to pull the sensors off the sides of the tank and put both in her water dish, so had to hide them. Temperature im iffy about. In a 40 gallon tank it reads a difference of 21⁰ on average from the bottom of the tank to the top. The hygrometer will range from 39% to 99%, although will point out again ky snake is a pain and likes to soak them in her water, might have messed it up. Analog hygrometers tend to hover 50% to 65%. So im blaming the snake instead of this product. She hates things on the glass of her tank.

I guess its a good thermometer. The humidity sensor (one of the main reasons I bought this) seems to be faulty. It has a constant 99% reading which is impossible in my tank. EDIT: so after letting it sit for a bit the humidity sensor seems to be working now. Which means I'm very happy with this product!

loving it. tested it with local weather, tested it with other thermometers, and another hygrometer at the local university. It takes a while for the hygrometer to settle in, in a new spot, or to show changes; but, once it does, I was only seeing a disparity of +1 at most. The thermometer was always spot on. Will be buying more for expanding my systems. Update 11/22/18 Ive now been using this for just under a month. I use this in a subtropical enclosure, at 75° ambiant temp/ approx 85% humidity. The temperature readings have seemingly stayed accurate. I've removed the unit and tested it jn other known Temps, variation has been +.5 every time. I can handle that. The hygrometer however is just a really poor unit. The resistor they use is of such low quality that the body of it seems to be quite water logged, or maybe it has just failed. keep in mind, I do not use a mist system or anything, no spraying, no standing water has touched the probe. My probe constantly says 99%, however. Now, if I could get this thing up to 99% without a fog or drops, even once a week, my plants and frogs would be in love. That just isn't something I can do though, because there is too much airflow. So, my conclusion. is that the hygrometer sensor probes are either being build with low quality and faulty resistors, or the hygrometer is just a lie altogether on this item. Anyhow, screw spending 5$ on items that don't work. Going back to the classic $20 Honeywell indoor/outdoor station

I bought this for use in my incubator with quail eggs. It works great. I sit the display on the outside, and the probes inside. The last display I put inside died from too much moisture behind the screen, this solves that problem nicely. So far with my latest hatch 33 of 39 eggs have hatched - I believe this to be from better humidity control. However this hygrometer does not have the same readings as the dial one that I also bought. I am not sure which is more accurate, but I base all my care off of the digital one's reading.

These are more accurate than I expected given the price point. I set up 17 of them all side-by-side and evaluated both the temperature and humidity readings over a period of about a week. These are very accurate, and they are very accurate to one another. Generally, between the 17 of them, the temperature in Fahrenheit was within .6° of one another. They also seemed quite accurate given the other thermometers that I have used in the past. They have a clip for mounting and also a magnet. The magnet is fairly strong, but it could be stronger. The humidity readings are generally within 1% of one another. That seems highly accurate to me also. I am very satisfied with these units.
