# Buy the A/RH2-O Today! 2% Outside Air Rh Xmtr - Over 1.8 million parts in stock ready to ship today!

**Manufacturer:** ACI  
**MPN:** `A/RH2-O`

The ACI A/RH2-O sensor converts a resistance change to a linear 4 to 20 mA, 0 to 5 VDC, or 0 to 10 VDC output. Its Advanced Ceramic Technology design overcomes the limitations of other resistance-based humidity sensors, allowing it to recover fully from condensation and maintain accuracy over time. Calibrated using a NIST Traceable Temperature and Humidity Chamber, this sensor is designed to be mounted flush to an exterior wall and features a gasketed cover and watertight fitting to lock out moisture.
