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

Perfect for my needs.,

So, these are what they say they are, but they firstly come with the batteries inserted, and thus two of mine were already flat. The quality of the housing is very reflective of the price. One unit did not function at all and one fell apart when fitting it into a enclosure. You need a 40mm Holesaw (actually 41mm) to make these fit into sides of containers or whatnot. Only clearly readable when directly above / in front of the unit. Again - reflective of pricepoint...

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.

It's ok and gives a reasonable reading, but with the 6 I received, a couple of them have readings that are not quite the same as the others, but it's only off by a little. As they say, close enough for government work.

Bought these for a 3D printer filament storage box and AMS, but am using the extra ones around the house. They are consistent with each other and easy to read. Happy with these.

Good value for the money

Excelente funcionan muy bien y me funcionaron todos

Humidity and temperature are clearly visible No misinterpretation Excellent device

Works great for humidity in my filament holders

Handy when monitoring refrigerating devices…battery operated…

Bought these for my 3d printer & filament. Have had them a while now & haven't had to change any batteries yet. I'm not sure how accurate they are but they all read the almost exactly same when sitting together in the same area. Maybe off by a point here or there but nothing crazy & they have helped me stay on top of changing out my silica in my ams. If I need more, Id buy these ones again for sure.
