C7232B Duct Mount CO2 Sensor

The C7232 stand-alone Carbon Dioxide (CO2) Sensors and Controllers are used for determining ventilation necessity with HVAC controllers and to manage the amount of fresh outdoor air supplied to maintain acceptable levels of CO2 in the space.

Overview

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.
Certifications:
  • CE
  • Underwriters Laboratories Inc. Listed, File No. E4436
  • cUL
  • C7232B: Flammability Rating, UL94-5V
  • C7232A: NEMA1
  • C7232B: NEMA3
