Theory of Leak Test | COSMO LEAK TESTER / COSMO ...

A pressure sensor corresponding to the range of the test pressure is used, lowering the resolution as the pressure gets higher, making the leak detection sensitivity worse. Temperature *Effects of the rise in temperature of the sealed air or changes in temperature are offset by being compared with MASTER, and are thus minimal.

10 Signs Of A Carbon Monoxide Leak | Alarm Inc.

Normally, the small amounts of CO released by heating equipment in the home are vented outside and do not build up inside, but when the air circulating your rooms and heating systems is not properly vented, or when there is a leakage that causes the rate of CO buildup to be greater than that of the venting, the high levels of carbon monoxide ...

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%.
