Extech RH35 Data sheet

RH35 Desktop Radar

Hygro-Thermometer Alert

Extech’s RH35 monitors Humidity, Temperature, and Dew Point
for the previous 24 hours and alerts users to indoor mold
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.

Applications:

- Commercial, retail and residential sites prone to mold

- Laboratories, R&D, server rooms, clean rooms and bio-pharmaceutical manufacturing

- Museums and storage and document archive facilities
