Description
This is a top-quality FORENSICS DETECTORS carbon monoxide detector with a built-in pump allowing for super-fast detection & response, point probe sampling, and continuous monitoring. Perfect for tracking the build-up of carbon monoxide in indoor environments and detecting any CO leaks, this carbon monoxide meter has a 32-bit microprocessor, color LCD, and graphing capability. The detector is USA NIST traceable calibrated in Los Angeles.
Another primary use is detecting carbon monoxide in cooling systems due to head gasket, cylinder head or engine block failures. Even though there is much less carbon monoxide when compared to carbon dioxide, it is still present; especially when the engine is not running at an optimum level. We also have to remember that, due to incomplete combustion, carbon monoxide will be present, notably since this is occurring before the catalytic converter(s)
The Science Behind It… Graham’s law states that the effusion rate of a gas is inversely proportional to the square root of the mass of its particles. In simple terms, this means that a gas with a lower molecular weight will escape through a small hole faster than one that has a heavier molecular weight. Since carbon monoxide (CO) has an approximate molecular weight of 28.01g/mol and carbon dioxide is closer to 44.01 g/mol, the CO will escape approximately 1.25 faster than CO2, thus (sometimes) making it easier to detect failures earlier on in the process. Said another way, since carbon monoxide molecules are smaller than carbon dioxide molecules, it is often easier to use this tool to detect traces of exhaust gases in cooling system.
