Veeco MS-40 / Edwards LT600
The industry standard MS-40 portable helium leak detectors

Fully automatic, easy to use, and highly accurate, these advanced design leak detectors are ideal for a broad range of applications including clean, oil-free systems for clean testing.
• Fully automatic operation, tuning and calibration reduces operator training and error
• Simple one-button start-up brings the system ready to test in less than three minutes
• Now assembled for us by VIC ( Vacuum Instrument Corporation ) the dual magnetic sector mass spectrometer provides resolving power of 14: So unlike some systems the Leak detector does not mistake adjacent peaks for helium

• Four modes of operation in a single unit: Direct, Reverse, Combination and with the right probe sniffing in atmosphere for highly flexible performance and applications
• Built-in test diagnostic display system error codes and isolate faults for trouble-free maintenance
• N.I.S.T. traceable temperature-compensated internal calibrator
• Fully CE certified - European units are built to CE certified specification (rest of world units may not be)
