Thiết Bị Cảnh Báo Nhiệt Độ, Độ Ẩm Để Bàn Extech RH35

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. The RH35 is perfect for commercial, retail and residential sites prone to mold. Complete with stand and 2 AAA batteries.
