SHR Series Wall Mounted Humidity Sensors
Schneider Electric’s SHR series of wall mounted humidity sensors measure the levels of relative humidity and temperature (if equipped) of the air inside a room. Temperature models feature a thermistor. The SHR humidity element is fully replaceable (HS2NX or HS2XX, available through Schneider Electric). To maintain accurate functionality, keep all vents free of dust, debris, etc.
