Kele CO2 and CO2/RH Sensors

 

The Kele KCO2 Series Carbon Dioxide Sensors measure CO2 levels in demand-controlled ventilation, air-quality monitoring, and other HVAC applications. The carbon dioxide sensor provides visual indication and analog output of CO2 levels. Designed for use in building automation systems, BAS, each CO2 detector is equipped with push-button calibration and an easily accessible calibration port for field maintenance. Optional audible alarm indication, LCD display, or relay output is available.
