product image

The Extech RH35 monitors humidity, temperature, and dew point from the previous 24 hours. It then alerts users to indoor mold hazard conditions starting with a frown icon warning if humidity reaches 60% RH. If the RH exceeds 65%, a loud audible alarm and bright flashing red LED will be triggered. The frown icon will also appear if the environment is too dry (<40% RH) where static electricity becomes a concern. The RH35 is perfect for commercial, retail and residential sites prone to mold. Complete with stand and 2 AAA batteries.
