Honeywell C7232 Carbon Dioxide (CO₂) Sensor C7232A1008

CO₂ sensor, wall-mount, display, 0/2 to 10V DC or 0/4-20mA output.

The C7232 Sensor and Controller is a stand-alone carbon dioxide (CO₂) sensor used to determine ventilation necessity with HVAC controllers. It measures the CO₂ concentration in the ventilated space or duct. The C7232 is also used in ventilation and air conditioning systems to control the amount of fresh outdoor air supplied to maintain acceptable CO₂ levelsin the space.

Features & Benefits:

• Used for CO₂-basedventilation control.
• Models with LCD are available that provide sensor readings and status information.
• Non-Dispersion-Infrared (NDIR) technology is used to measure carbon dioxide gas.
• Device provides voltage or current output based on CO₂ levels.
• Models available with SPST relay output.
• Automatic Background Calibration (ABC) algorithm based on long-term evaluation reduces required typical zero-drift check maintenance.
