Honeywell C7232 Carbon Dioxide CO2 Sensor C7232A1024

CO₂ sensor, include display, wall-mount, 128 mm H x 80 mm W x 25 mm D, no logo.

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

Features & Benefits:

• Used for CO₂ based ventilation control.
• Models available with LCD that provides sensor readings and status information.
• Non-Dispersion-Infrared (NDIR) technology 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.
