Leak detection in pressurized devices the sensitive test Leybold

Devices operating above atmospheric pressure, such as valves for the oil and gas industry, are an important application of leak detection. Other uses include checking the leak integrity of containers holding biological and nuclear substances, and even the performance of cartyres. Here's a quick overview of the sensitive test of a helium checker — fundamental to leak detection inpressurizeddevices. Sensitive test of a helium checker There are manymethodsof leak detection, such asabubble test or pressure droptest, but none can compete with the sensitivity and the ability to pinpoint a leak that a Helium leak checker can offer. Additionally,a heliuminstrument allowsforboth quantitative and qualitative measurements.A helium or, more precisely, a Helium 4 leak detector is essentially a tuned mass spectrometer which detects this gas and has the further option of identifying Helium 3 (used in cryogenics) and hydrogen. The unit has appropriate pumps supplied making it portable, with only mains...
