Crossfire CFC2 CO2 Monitor


Model CFC2 

The Crossfire CFS CO2 sensor with 25 feet of cable may be plugged into the CFC1 controller at any time without any further setup.  The CFS CO2 sensor also includes a light and temperature sensor.

Together, the CFC1 controller and CFS remote CO2 sensor provide an affordable dual zone CO2 monitoring and control system 




  • Plug and Play: The Crossfire CO2 controller will automatically detect the presence of the sensor and start to use it.  The readings and information for this sensor will be shown as #2 on the controller LCD
  • Precision CO2 sensor: Dual Wavelength NDIR sensor technology with altitude and temperature compensated.  Designed specifically for greenhouse applications
  • Light sensor to disable CO2 control if lights are off
  • Temperature sensor for compensation and high temperature shut-off
