Carbon Monoxide (CO) Detection - System Sensor

Electrochemical detectors are the newest, most reliable CO detectors available. They take the most accurate readings of CO, from low levels of CO that may be hazardous over long periods of time to high concentrations that present an immediate danger. They are also less prone to false alarms than other types of CO sensing technologies. End-of-Life Notification The CO1224T and CO1224TR are ...
