Veanic 3-Pack Mini Hygrometer Thermometer Fahrenheit or Celsius Meter Digital LCD Monitor Indoor Room Round Humidity Temperature Gauge for Humidors Home Greenhouse Babyroom Reptile Incubator

These are lousy so called hygrometer/ thermometers. I purchased it for a dry box for my 3D printer filaments, but is useless. The Thermometer part could be ok, but the humidity indication is way off. I put them in a sealed container with a DHT22 and left them for 2 days. At the humidity level of 12% one was 31%, the second was 21% and the third 29%. In the room, kept in the same spot the differences were slightly greater, but not in the same order.So if you want to use them to have an actual measurement, forget about it.Would not recommend it.

If you want a solid inexpensive product with customer service that is out of the World by these temperature in humidity gauges perfect way to start off your grow room one of them malfunction out-of-the-box within six days I had a brand new set of 3 and none of the five I have right now give me any trouble great products

Exactly what I was looking for. The temperature can be switched from °C or °F pretty easily. Worked right out of the box and seems to be accurate. The only downside was they lack a way to attach these to the tank wall.

These thermometers are not accurate, they are of by 15 degrees.put them side by side and one of the is at 77 degrees-F and the other is at 65 degrees-FAnd the real temperature is 58 degrees -Fthey are not accurate at all

These are junk. I tried to compare 2 of the 3 and they were off by about 4 degrees. You cant calibrate them. I would not use them for incubators.

After using a boveda calibration kit all three of these read differently with only one being within a couple percentage points.

Works as designed. Numbers don’t always match each other. But good enough for my purposes.

Nice little hygrometer.
