CO and CO2 – What’s the difference? |

The molecular weight of CO is , where the molecular weight of CO2 is This means that the CO2 gas is much more dense than CO. CO2 will collect near floor level while CO will collect closer to the ceiling. OSHA lists danger levels for CO beginning at 35 ppm, and for CO2 starting at a 5,000 ppm time-weighted average.

Carbon Monoxide Sensor Cross-Sensitivities Alcohols, VOCs ...

CO sensors can become saturated with target gas CO. 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 ...
