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

So I ordered these due to their price for my gun safe. I kinda expected these to be you get what you pay for, boy was I wrong. This is a 2 pack to begin with but not only do they come with batteries already in them they come with a spare set of batteries. These are also built with mounting retainer clips, so you can insert them into whatever you are putting them into. As you can see they vary slightly but their variable is so small its dismissive. I tried these in different environments along with testing them along side an outside digital device I already owned and again spot on. You truly cannot go wrong with these, well made and a price thats unbeatable.

I got these for the inside of my bearded dragons tank, and they adhere to the tank, easily or easily to read seem to be accurate

Both broke on day one. The little plastic piece that keeps the back on and the batteries in broke almost instantly.

I wanted these for a cigar humidor and to use on a shelf in my room adjacent to the humidor. I was wary based on some reviews and the price point. In short, they seem to work just fine. My small humidor has an analog hygrometer which seems to read about 4% lower than this digital one placed inside the humidor (i.e. analog 68 and digital 72.) Which is more accurate I dont know, but that they basically agree tells me theyre basically working. The adjacent one reads around 58-60 as conditions change in the house. Theyll be interesting to monitor as summer comes on and we install the ACs. They came with batteries installed AND spare batteries, a huge plus since they take button cells. Also, at least in the ranges Ive seen them operate, the values change in increments of 1, not large chunks like switching from 54 to 69 etc as I read in another review. Cheap product, so your mileage may vary

Have compared to other various hygrometers in a humidor, and these are spot on within 1%.

It’s the second time I’ve ordered some of these digital hydrometers and they really work great and I was not expecting to have the extra batteries which is a huge plus for me. It’s always hard for me to keep up with batteries and now I have some extra ones, keep up the great work

Alot of reviews show 2 very different readings. That seems to happen when you move them or touch them etc. But if you set them down and leave them for a few minutes they even out because mine are basically identical and work just fine.

Works amazing. Helped a TON with not having to guess the % my humidity was at.

The thermostat is very good very accurate but the adhesive that it came with doesn’t last long and doesn’t come off. But overall the thermostat is good! :)
