The Agilent / Varian 959 Helium Mass Spectrometer Leak Detector is a portable, self-contained mass spectrometer helium leak detector using a wet (oil-based) oil-based mechanical vacuum pump.

The Agilent / Varian 959 provide clean and automatic leak detection utilizing the Contra-Flow™ vacuum system design that allows testing at high test point pressures.

The Turbo pump is used to achieve very high vacuum in the spectrometer tube. The roughing pump is located on the cart below the leak detector. An optional power probe accessory allows the leak detector to operate as a quick-response, high-sensitivity sniffing leak detector.
