The Varian 956 Porta Test II automatic leak detector is a state-of-the-art, totally automatic leak detector that is suitable for portable or fixed applications. In addition to its one button pumpdown and test sequencing, the 956 unit also has automatic calibration and zeroing procedures which eliminate routine operator intervention thus ensuring correct operation. A bidirectional RS-232 interface allows data logging of the test results and remote setting of machine parameters. The Varian 956 Porta Test II Automatic Leak Detector is based on the Contra-Flow™ vacuum system design and is fully protected from accidental air inrushes and power failures. An optional Fast Sniff Tester (FST) unit can be built into the Varian 956 Porta Test II Automatic Leak Detector. This allows testing of helium-pressurized vessels or components while leaving the main test port available for evacuation-type leak detection work. Unique software provides automatic zeroing and calibration while the 956 is being used in the Sniffer mode.
