______________________________

The Varian 947 mass spectrometer leak detector is a high sensitivity, high speed lead detector which utilizes state-of-the-art technology & simplicity to provide the user with a relatively easy-to-operate, high technology testing device.

While the 947 and 948 leak detectors provide high sensitivity for detecting small leaks, they can leak test to 10 atm-cc/sec. An atmospheric gross leak option allows searching for helium leaks with test port pressures as high as 760 torr. The Multi-Test option for the 947 includes atmospheric gross leak capability and a volumetric expansion procedure that detects massive leaks even if all of the internal helium has escaped from the part prior to the test. Multi-Test can be used with parts that have net internal volumes greater than 6 cc.
