Product Overview: Even with today's complex technology, it is, for all practical purposes, impossible to manufacture a sealed enclosure or system that can be guaranteed leak proof without first being tested. Through the use of modern mass spectrometer leak testing techniques, as implemented by the Varian 979 Helium Leak Detector, leak rates in the 10−9 std cc/sec range can be reliably detected. The Agilet 979 is a wide-range Helium Mass Spectrometer Leak Detector. It is comprised of a turbo-molecular high vacuum pump, spectrometer tube, valve block, Varian Vacuum Technologies’ Platform leak detector electronics, and an operator interface in a stylish, yet rugged housing.
