The Varian 956 Portable Helium Mass Spectrometer Leak Detector is a microprocessor-controlled leak detector utilizing state of the art technology for easy operator interface. 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 enhanceing the user-friendly environment. Control keys such as START, VENT, AUDIO, and AUTO/MAN keys appear on the right side of the front panel for easy access while programming or special function keys are on the left side under a cover.
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.
For unique applications and for the expert user, critical system parameters are programmable to make the 956 portable leak detector fit any leak detection application.
THERE ARE NO RETURNS ON THIS PRODUCT.
