The AG01 carbon monoxide (CO) sensing element is designed to work with the Veris GWN series gas platform unit to provide accurate monitoring of CO levels. Common sources of CO include automobile exhaust from gasoline engines, gasoline powered furnaces, gasoline powered water heaters, and gasoline generators. The sensor is calibrated at the factory, so no field calibration is needed. The AG01 is warranted to meet accuracy specifications for 2 years after the date of manufacture.
