CWL carbon dioxide sensors maximize energy savings, while ensuring optimal ventilation. The sensors allow ventilation systems to be controlled by the amount of CO2 present in a space. The CWL Series detect fluctuations in CO2 levels and signal ventilation systems to provide an inlet of fresh air optimal for the space at a given time saving energy and ensuring tenant comfort.


  • Controlling ventilation in response to occupancy
  • Facilitating compliance with ASHRAE 62.1-2004 standard for air quality
  • Office buildings, conference rooms, schools, retail stores, etc.

Microprocessor design increases accuracy and reduces installation time

  • Non-dispersive infrared technology (NDIR) repeatable to ±20 ppm ±1% of measured value
  • Innovative self-calibration algorithm...easy to maintain
  • 5-year calibration interval (recommended)
  • Low ambient sensitivity
  • Field-selectable outputs for operation flexibility

Revolutionary direct duct mounting design

  • Integrated transducer and probe...eliminates the need to install a separate pick-up tube
  • Snap-on screws required, making installation and service a snap
  • Adjustable duct probe...simplifies installation and airflow monitoring
  • CO2, humidity, and temperature sensing all in one compact device...fewer units to buy and install
