Honeywell Wall Mount CO2 Sensor with LCD

FEATURES

The C7233A series Wall Mount CO2 sensor provides analog or digital output signals for demand control ventilation systems. It ensures improved indoor air quality while minimizing energy costs.

LED DISPLAY
• The C7233A1008 includes a flush face membrane and attractive white LED CO2 ppm display. All variants have red LED notification activated when CO2 level exceeds preset threshold.

PROGRAMMABLE SPST RELAY
• Programmable CO2 threshold setting to activate relay for ventilation signal or damper control.

SELF- CALIBRATION
• Automatic Background Calibration (ABC) algorithm ensures accuracy for 10 years or more.

SELECTABLE OUTPUT
• Analog output range is selectable 0/2 - 10 VDC and provides accurate proportional linear signal though entire sensing range 0 - 2000 ppm.

ADVANCED SENSING
• Highly accurate and reliable Non-Dispersion Infrared (NDIR) technology for CO2 sensing.

ELEGANT DESIGN
• Ultra compact size and elegant design with easy cleaning via smooth front membrane design.

IMPROVED VENTILATION
• Effective CO2 sensing supports demand controlled ventilation to balance indoor air quality with energy savings.

TEMPERATURE SENSING
• Optional accurate temperature sensor variant is available.
