ACI A/RH3-R Room Humidity Transmitter 3% MA/VDC

The ACI Relative Humidity with Thermistor Duct Series uses a durable capacitive sensing element with a hydrophobic filter for strong resistance to moisture, dust, dirt, oils, and chemicals. It offers flexible configuration with DIP switches for output selection and can operate on AC or DC power. The unit includes built-in 0%, 50%, and 100% test modes to verify proper operation and wiring, along with easy field calibration via DIP switches—no sensor replacement required. Designed for harsh environments, it features a weatherproof enclosure, conformally coated circuit boards, and a stainless-steel filter for added protection, ensuring long-term reliability.
