Natural Gas & Carbon Monoxide Detector CHCO

Natural Gas & Carbon Monoxide Detector CHCO

When methane and/or carbon monoxide are sensed the detector sounds an on board audible alarm and changes over a volt free contact relating to the type of gas sensed. These volt free relays can be used to isolate the electrical supply to gas solenoid valves or give a remote indication of an alarm. The alarm threshold for methane is 10% LEL and for carbon monoxide is 300ppm. The CHCO also has a separate carbon monoxide relay alarm facility which gives a relay output at 30-50-100ppm of carbon monoxide based on time weighted average function.
