Series Description

The ACI A/RH1 Series relative humidity transmitters utilize a capacitive sensing element to deliver a highly accurate, proportional 4 to 20 mA, 0 to 5 VDC, or 0 to 10 VDC output for 1% measurement. It is available for room, duct, outside, and stainless steel wall plate applications. The A/RH1 Series is accurate over a customer specified 20% range (either 50 to 70%, 60 to 80%, or 70 to 90% RH). On board DIP switches allow the user to select the desired output signal and can be powered by AC or DC power sources. Each A/RH1 Series humidity transmitter is calibrated using a NIST Traceable Temperature/Humidity Chamber. Three and five point NIST calibration certificates are available and optional.
