MS-40GT

PORTABLE HELIUM LEAK DETECTOR

PORTABLE DRY/WET HELIUM LEAK DETECTOR

The MS-40GT available either wet or dry pumping package is fully automatic, easy to use, and highly accurate. These advanced leak detectors are ideal for a broad range of applications including clean, oil-free testing.

Helium that is present in a test object is drawn into the unit (either through the test port or through the sniffer valve), isolated and detected by a mass spectrometer, and converted into an electric signal. The electric signal generated is proportional to the leak rate of the helium drawn through the leak found in the test object. Once this signal is amplified, the signal is displayed as a leak rate on the User Panel of the MS-40GT.

It also meets the stringent requirements for robustness, reliability and ease of maintenance that are essential in any industrial environment..
