Package leak detectors |

The LEAK-MASTER® PRO uses CO 2 as a trace gas. The use of CO 2 is a particularly cost-effective method compared to helium or hydrogen. Products which are packaged under protective gas contain CO 2 in most cases as a component of the protective atmosphere - other products produce CO 2 themselves. An adjustable vacuum is generated in the measuring chamber. The pressure difference between the ...

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

However, the hydrogen leak mostly affected the CO readings, and not the readings from the LEL sensors in the instruments we are currently using. We would pick up 0-5% LEL from time to time, but pretty constantly stay at about 50-250 ppm CO even though we knew that could not be right since CO can only be present as a byproduct of combustion from a heater stack or vehicle exhaust. The wind ...
