ACI 122669 Room Humidity Sensor with 10K Thermistor

The ACI 122669 (A/RH2-CP-R) is a professional-grade room relative humidity sensor with integrated 10K Type II thermistor for temperature monitoring in commercial and industrial HVAC applications. This dual-function sensor provides accurate humidity measurement with ±2% accuracy and features selectable output signals for maximum flexibility in building automation systems.

Key Features:

• Selectable output signals: 0-5 VDC, 0-10 VDC, or 4-20mA (default) via onboard DIP switches
• ±2% relative humidity accuracy for precise environmental monitoring
• Integrated 10K Ohm Type II thermistor for simultaneous temperature sensing
• Thermoset polymer capacitive sensing element with factory-fitted hydrophobic filter for moisture resistance
• Field calibration capability in ±0.5% increments using onboard DIP switches
• Compatible with AC or DC power sources
• Beige ABS enclosure designed for room installation
• Multilayer sensor construction resists dust, dirt, oils, and common environmental chemicals

Designed for building automation systems (BAS), this sensor delivers reliable long-term performance without the need for field replacement. The capacitive sensing technology and rugged construction make it ideal for commercial buildings, industrial facilities, and HVAC control applications where accurate humidity and temperature monitoring are essential. Made in the USA and backed by ACI's five-year warranty.
