COF is a detector intended for demand-controlled ventilation in parking garages and road tunnels etc. The detector is installed for both safety and energy-saving reasons. It measures the carbon monoxide concentration using an electrochemical method of measurement characterised by high selectivity even in low concentrations. The output signals are linear representations of the gas concentration.
