Mini Hygrometer Thermometer 2PCS Mini Digital Humidity Gauge, AikTryee Hygrometer Indoor Humidity Monitor, Temperature Humidity Gauge Meter for Humidors, Greenhouse, Garden, Cellar, Closet, Etc

Works as described. Mine were about 5 degrees off on temperature and humidity. Battery life was meh at about 6 months of 24/7 operation. Decent product for the price. Simple to use and easy to read display.

I ordered the (2) pack of the hygrometer/temp gauges to use for each of my cars. I decided to test their accuracy against other digital weather gauges I have in my house and each other. I set the 2 up near the centralized weather unit for comparison and allowed them to stabilize for 3 days. I’ve supplied a photo of the comparisons. The reading differential to each other is 0.3 degree F. and 2%. The 2%, 40% & 42%, differential between each is not within the +/- 2% advertised. The hygrometer reading 40% vs. 39% of my home weather hygrometer is within tolerance and obviously the 42% is not with its sibling or the weather hygrometer. The temp on the two siblings vs. the weather gauge is within 3%. I ordered the gauges for my cars to analyze a dry cough I’ve been having that I believe is related to the humidity differential to exterior air and house air. The price of the (2) gauges are very inexpensive and are relatively accurate. The surprise was that the two sibling hygrometer units didn’t agree within advertised tolerance. I expected the siblings to be relatively close to the weather station and closer to each other. I didn’t measure the response time and accuracy, other than the 3 day stabilizing period. So the overall rating of 4 stars reflects the 3 star rating for the tolerance differential from the advertised +/- 2% tolerance between the sibling hygrometers. The unit is good general information of temp and humidity certainly for the price.

It is not accurate at ALL. Places it in the incubator with a govee just to see and while my incubator and govee showed 99.5 temp and 40% humidity, these showed 80 temp and 60% humidity on one and 82 temp and 70% humidity on the other. They were both placed right next to the govee in the same spot so should have read the same as govee or at LEAST read the same in both of them. They both read different from each other and not even close to the incubator or govee. Not worth it

I got this to go in my guitar case. I had alternately been over-humidifying and under-humidifying, neither of which was ideal. Where to mount it so that it wouldnt rattle around? I decided to wedge a piece of plastic from a notebook cover into the area near the storage box of the case. Then I used Velcro to attach the humidifier to the plastic, so that I could get if off to change the batteries. Good luck.

I bought this for a snail enclosure. It fell off the wall in approximately 3 hours and it had no reading on the screen. After drying it off the screen worked again. Apparently it does not work in a damp humid enclosure. It was a 2 pack and I tried both with the same results. In a dry enclosure it may work just fine.

Product exactly as described, came with double sided tape pads, large numbers and easy to read; measurement are consistent between the two within 1 degree and consistent with my side of tank heat indicator strip within about 3 degrees. For the price, this is a reasonable set that will give you a good idea of temp and humidity. May not be exact, but then again... these things rarely are exact. For my purposes, the 1-3 degree difference is not a big deal. Also came with extra batteries which is a huge plus since they are little button batteries and I would have to order more. Now I can change them when they go out and go ahead and order new ones without having to take them out of the tank, see what kind, and then wait several days to get them. Would buy again.

These are tiny yet I’m still able to read them. I love them. I use them in my leopard geckos tank. I haven’t used the adhesive to put it up on the tank. I just stuck them inside on my hot and cool side. Works awesome. Same temps as what my heat gun is saying. Love that there was extra batteries in the package too!!

Got these for my incubators. They seem pretty accurate. Theyre small, but easy to read.

I bought 2 of the mini hygrometers and they are giving the same readout that I’m getting from my larger, costlier devices. The size is perfect for placement into mason jars. The additional included batteries were a nice bonus too! There are what appears to be clips on the side that I am unsure of how to use, but am happy with placing them either with the included double sided adhesive stickers, or simply standing/laying down.

I grow plants in a tent, and have to check the humidity levels. These are a great value, but they dont last very long. One lasts, about the time of each grow to harvest, so I have to buy a new pair, about once per year, if I do two harvests per year, but these dont cost very much, so I think thats fine The downside is the adhesive tape, barely stays on, so be careful where you put it, or use another adhesive. it also makes it near impossible to change the battery, but these dont last long, so that isnt much of an issue The display is really easy to read, and its very accurate. Thats why I dont mind replacing them every year. These are cheap, but the value of accuracy, is paramount when growing things in a tent
