ZQJ-2000 Helium Mass Spectrometer Leak Detector Introduction
Helium Mass Spectrometer LeakDetector is a gas industry term that uses helium or hydrogen as a leak gas, and uses a gas analyzer to detect helium for leak detection. Helium has a low background noise, small molecular weight and viscosity coefficient, so it can easily leak through and leak easily. In addition, helium is an inert gas that does not corrode equipment, so helium is commonly used as a leak gas. This gas is sprayed on the container to be inspected connected to the gas analyzer (adjusted to the working state that only reacts to helium). If the container has a leak, the analyzer will respond, so that the leak is located Gas volume. Features
