Product review (5 stars): An accurate way to read the humidity in each room of your house.
By moving this Extech Humidity Meter we can now see the humidity in each room of our house and found that the humidity was a bit too high in the basement. We are now installing a dehumidifier downstairs to take care of the humidity problem. By keeping the Meter in the basement after the dehumidifier is working we should be able to set the dehumidifier at the correct setting to achieve the humidity level we need since the dehumidifier does not have a meter on it. It will take the guess work out of setting the dehumidifier.
