ACI ACI-RH1-D-010 Duct Humidity Transmitter 1% MA/VDC

The ACI Relative Humidity Duct sensor uses a durable capacitive sensing element with a hydrophobic filter to resist moisture, dust, dirt, oils, and chemicals. With DIP switches to select output signals and supports both AC and DC power. Built-in test settings (0%, 50%, 100%) help verify proper operation wiring. The sensor allows easy field calibration without replacing parts, improving flexibility, and long-term reliability. Duct Design includes a weatherproof enclosure, moisture resistant coated circuit boards, and a stainless-steel filter for protection in high humidity environments.
