The VS Series Helium Mass Spectrometer Leak Detector is an advanced device used to detect and measure leaks in various systems that use helium as a tracer gas. Helium gas is inert, non-toxic, and has a small atomic size, allowing it to escape even through the smallest leaks, making it safe and non-hazardous. The leak detector separates helium in the tested environment and measures the amount of helium drawn using its mass spectrometer, allowing for high-precision leak detection. This precise measurement capability makes the VS Series ideal for critical leak detection in industries such as aerospace, automotive, and semiconductor manufacturing.
