Vacuum Leak Detectors and Helium Leak Detectors

Helium leak detectors are the ideal solution for leak detection and leak-tightness testing under vacuum. The test gas Helium is safe and a small, light molecule which is suitable for detecting micro leaks. The detection range of Helium in vacuum tests lies between 10-2 and 10-13 Pa m 3 /s. Helium leak detection is extremely accurate, quantitative and repeatable.
