Conventional Carbon Monoxide - System Sensor

(CO) Detectors The system-connected CO1224T and CO1224TR CO detectors with RealTest® provide early warning of dangerous CO buildup by using electrochemical sensing technology to measure CO levels in the air. If a dangerous amount of CO is detected, then the CO1224T / CO1224TR will alert residents by sounding and flashing a Temp-4 signal alarm.

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

The reason that CO sensors are potentially susceptible to hydrogen (H2) interference is the reaction that is used to detect gas. Hydrogen is actually part of the detection reaction. The relative response to hydrogen depends on the brand and model of sensor. Some commonly used CO sensors show a relative response to hydrogen as high as 60%.
