ACI Room, Duct, and OSA 3% Humidity Transmitters A/RH3 Series

ACI Room, Duct, and OSA 3% Humidity Transmitters

 

The ACI A/RH3 Series relative humidity transmitters are specifically designed for use in HVAC/BAS applications and deliver/or have a proportional 4 to 20 mA, 0 to 5 VDC, or 0 to 10 VDC output for 3% measurement. it is available for room, duct, outside, and stainless steel wall plate applications. The A/RH3 Series has on board DIP switches which allow the user to select the desired output signal and can be powered by AC or DC power sources. Each A/RH3 Series humidity transmitter is calibrated using a NIST Traceable Temperature/Humidity Chamber. Three and five point NIST calibration certificates are available and optional.
