ACI A/RH3-D Plate Humidity Transmitter 3% MA/VDC

The ACI Relative Humidity Duct sensor is built for dependable performance in harsh HVAC and industrial environments. It uses a moisture-resistant thermoset polymer sensing element with protective hydrophobic and stainless-steel filters to resist dust, dirt, oils, and environmental contaminants. The sensor supports both AC and DC power and includes onboard DIP switches for easy output selection, testing, and field calibration without replacing the sensing element. Its weatherproof enclosure, gasketed cover, and coated circuit boards provide added protection in high-humidity applications, while optional three-point NIST calibration certificates are available for verified accuracy.
