Indoor/Outdoor Hygrometer Accuracy Test

Do you suspect that the temperature or humidity is inaccurate or reading incorrect? 

Here's how to test the accuracy of your Hygrometer.

If you just unpackaged this device, we first recommend giving the device a couple hours to acclimatize to its atmosphere before comparing the readings. 

If you want to check the humidity accuracy of your device, you can try doing a humidity salt test. Instructions on how to perform a salt test can be found in the link below:

If you have another device that is known to be accurate such as a home thermostat or another hygrometer, you can try a side-by-side comparison test.

Please keep in mind most of our devices have a +/- 2 F temperature tolerance and a +/- 3% humidity tolerance, so as long as they are within this range of each other, this is considered accurate.

If after testing the readings are still inaccurate, please provide us with your Order ID number and full shipping address and we will look into replacing this for you if it is within warranty.
