2-Pack Mini Digital Hygrometer Gauge Indoor Thermometer, LCD Monitor Temperature Outdoor Humidity Meter for Humidors Greenhouse Jars Incubators Guitar Case, Display Fahrenheit (℉)

Was smaller than expected but thats my fault for not paying attention to pics and clear specs. Still easy to read despite being less than 2x2 inches! Works well, seems accurate! If just need something to tell temp in an area its a very cost effective option and it displays accurate humidity also.

I recently purchased a couple of small incubators and I was questioning the accuracy of their digital thermometers. I purchased these as backups to double check the accuracy and I confirmed what I thought. The incubators were not accurate. These are great little thermometers that are easy to use, easy to read and accurate. Plus they came with extra batteries.

Works well but the temp is off by a couple of degrees. Small compact form and large easy to read numbers.

I have purchased these multiple times. I use them to monitor the RH in bins that I keep 3D printing filament in. Never had a single issue. They only display down to 10%, but as long as the bins stay below 10%, I'm happy.

Decent for the price.

I velcroed this inside my guitar case so I can monitor the humidity all winter long. It's been great and helped me keep my guitar properly stored all winter long.

I am going to buy more.. I used these in a 3D printer filament storage and dispenser box I built as some 3D supplies will absorb water from the air and make the prints with lots of flaws.. these work great and compare to each other exactly as well as a calibrated instrument.. I can't believe how inexpensive these are.. Dont guess any more just get them and thank to the supplier from Amazon.. quickly received order and comes with 2 spare batteries... That was a nice touch.

Both became unusable within days. The battery backing comes off if you pick it up to move it or read the small font and the batteries fly out immediately. Hard to get the back on securely. When I decided I would tape it closed I couldn't find where the batteries went when they fell out. It also shows the humidity as the big number and temp is the smaller one. Seemed kinda backwards or just not what I'm used to
