Honeywell Carbon Dioxide Sensor C7232 Series

Honeywell Carbon Dioxide Sensor

 

The Honeywell Model C7232 carbon dioxide sensor measures CO2 concentration in a ventilated space or duct. These CO2 sensors are designed for use in building automation systems, BAS, and HVAC systems to achieve building ventilation control. These easy-to-install wall-mount or duct-mount sensors provide long term CO2 monitoring at a low cost. Each sensor is compact in size and has selectable ranges. They have an analog and relay output, use non-dispersive infrared (NDIR) technology, and feature a unique corrosion-free sensing chamber for accurate, stable CO2 sensing. Models are available for wall and duct-mount applications, with or without an LCD display, and with or without the Honeywell logo.
