Description

Varian’s 956 portable helium mass spectrometer leak detector is a microprocessor-controlled leak detector. A 48-character alpha-numeric display on the front panel is used to spell out information to alert the operator of the current status of the leak detector. The alpha-numeric displays also interact with the front panel keys enhancing the user friendly environment. Necessary valving takes place automatically as the leak detector moves through various ranges tracking the helium signal and the test port pressure. Additional features such as Auto Calibration, Gross Leak, large rough pumps, etc., make this portable leak detector a completely integrated package.
