HONEYWELL C7632B1002 Duct mounted Non-dispersive Infrared (NDIR) Carbon Dioxide Sensor with Honeywell logo. The Carbon Dioxide (CO2) Sensors offer a fixed 0-2000ppm and fixed 0-10Vdc output. No adjustments are necessary. Like the C7232 sensors, these are for use in determining ventilation necessity with HVAC controllers. The sensor measures the CO2 concentration in the ventilated space or duct. The sensors are 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 Non-Dispersion-Infrared (NDIR) technology used to measure carbon dioxide gas. Gold-plated sensor provides long-term calibration stability. Fixed 0-2000ppm, fixed 0-10Vdc output. Used for CO2 based ventilation control (Demand Control Ventilation (DCV)). Automatic Background Calibration (ABC) algorithm based on long-term evaluation reduces required typical zero-drift check maintenance.
