DESCRIPTION
The ACI A/RH2 Series Relative Humidity Transmitters utilize
a capacitive sensing element to deliver a proportional 4 to 20 mA,
0 to 5 VDC, or 0 to 10 VDC output. It is available for room, duct,
outside, and stainless steel wall plate applications. The A/RH2
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/RH2 Series humidity transmitter is calibrated using a
NIST Traceable Temperature/Humidity Chamber. Three and five
point NIST calibration certificates are available and optional.
