Extech's RH35 monitors Humidity, Temperature, and Dew Point for the previous 24 hours and alerts users to indoor mould hazard conditions starting with a frown icon warning when humidity reaches 60%RH.
When 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 mould.
