CO100Ar – Carbon Monoxide Sensor

Gas Detection

The CO100Ar is an electrochemical sensor which provides a signal proportional to the levels of carbon monoxide in its vicinity. It then provides a 4-20mA signal back to any one of the Duomo detector panels listed above. This clever sensor also has a Time Weighted Average (TWA) function and can, therefore, provide a 20mA signal if the levels of gas stay above a lower concentration of gas for a given period e.g. 30ppm for 120 minutes. The CO100Ar can typically be used as part of a complete gas detection safety kit for a boiler room alongside our 'Related Products' (see below).
