Vacuum Leak Detectors and Helium Leak Detectors

Stationary high-performance leak detectors are used where extremely short cycle times and fast cleanup of Helium background are required. Our leak detectors of the ASM 192 and ASM 1002 series are used in applications ranging from large-scale testing of electronic components for leak tightness up to highly sensitive applications in vacuum and medical technology or research and development.
