The Varian 947 and 948 leak detectors have single button pass/fall test cycling and automatic spectrometer tuning and calibration. The Contra-Flow vacuum system arrangement uses a valving manifold that has been designed for fast cycle times and reliability.
In addition to the front panel LED leak rate, pressure, and condition displays, information is also available on analog, parallel I/O, and RS232, remote interfaces.
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.
