2Z 10-Pack Mini Digital Humidity Thermometer Hygrometer Temperature Meters Gauge Indoor Lcd Display for Guitar Reptile Greenhouse Humidor Cigar Home Room Black

these are acceptably accurate ( /- 5% RH, /- 2 degrees F) compared to other instruments, and for there money are surprisingly accurate. I have them all over the house now :)

I have bought these before several years ago. Most of them are still working. Most of the 10 unit measure with 3 points of each other, you always get a couple ones that might be 3 points off the center measurement either way. Still, close enough.

Works great. Will purchase more in the future.

This item works great, and fits in the jars easily!

These are small and nice for keeping in various rooms in the house. They seem to be accurate so you can know the humidity and temperatures in different places.

These thermometers work great, great price for 10 of them. I have 2 in each reptile cage to verify temperatures. No complaints!

the temp/humidity guages were exactly what I was wanting and expected. Downside is all of them were working wasting battery life, there was not plastic strips to pull like other electronics. They are working great in my terrariums the extras I have I just removed batteries for future use. EXCELLENT

All but one of the gauges are within the tolerant accuracy ranges. They will do the trick. All good here.

As soon as I took them out of the package all displayed different relative humidity and temperature readings. The picture shows the temperature in Fahrenheit, but the meters are set to Celsius and cannot be changed. to convert the temp a calculation must be made C x 9/5 32 = F. I am old school and want to know the temp in F. Price is right and they come with batteries.

defective. off by like 12° all 10
