CO and NO2 Sensor KCO-NO2 Series

CO and NO2 Sensor

 

The Kele KCO-NO2 sensor is designed to monitor carbon monoxide and nitrogen dioxide levels in ambient air. It is constructed with a rugged, powder-coated steel enclosure for protection against impact and chemicals. The hinge cover version can be locked. The Kele KCO-NO2 effectively measures and reduces toxic exposure in parking garages, loading docks, and other vulnerable environments. Its operation range is 0-200 ppm for carbon monoxide and 0-10 ppm for nitrogen dioxide. The CO and NO2 sensors are field replaceable with calibrated modules.
