Why is hydrogen such a big issue for CO sensors? | GfG ...

Carbon monoxide that enters the sensor is oxidized at the surface of the sensing electrode, causing the potential of the sensing electrode to rise relative to that of the counter electrode. Current collecting filaments connect the electrodes with the external pins of the sensor. The instrument supplies power to the sensor, and interprets the output of the sensor by readings obtained through the external pins. In twoelectrode sensor designs, the potential of the sensing electrode …

If enough CO enters the sensor beyond maximum range (that listed in the instruction manual), the sensor is unlikely to be able to process all applied gas. When this scenario occurs, the electrolyte becomes saturated. A saturated sensor will continue to show high gas readings until the gas can be processed from the electrolyte. If saturation occurs, allow the instrument
