6-Pack Mini Hygrometer Thermometer Digital LCD Monitor Indoor/Outdoor Humidity Meter Gauge Temperature for Humidifiers Greenhouse Reptile Fahrenheit(℉)/ Celsius(℃)

Good value when purchased in bulk. I bought a 6 pack to use in filament storage containers All 6 read accurately and were synced within less than 0.6 percent of each other. Impressive. They have a button on the back for displaying temp in C or F.

These seem very accurate for checking humidity level. I use a bunch of these for keeping check on my 3d print filament. They are a great size and value for the money

I use these to keep track of the temperature and humidity for a 3-D printer filament. They are fairly accurate to the other ones that I already have. My only complaint would be that there is no tab between the battery and the contacts so the battery is already being used while I’ve been sitting in storage before shipping. Other than that, they fit right into the AMS print.

Works great

One of the six was DoA. Only half the LCD worked. But I needed the rest so I wasn't going to send all six back to get one replaced.

Using for 3d printing and my AMS. They seem accurate, but feel a tad cheap. I can't review for long term, but short term they do exactly what I need them to do.

I have ordered over 50 of these hygrometer. Only 1 battery had died early since using them. The % of moisture readings vary a little between all of them but well within a reasonable percentage of each other.

Good value for the money

Excelente funcionan muy bien y me funcionaron todos

Works great for humidity in my filament holders

Humidity and temperature are clearly visible No misinterpretation Excellent device

Works great!!!

Overall seems pretty accurate. Every one was off a little but within a few percentage range.
