- Fully Mobile Leak Detector
- Sensitivity Ranges: 10-4 through 10-8 atm cc/sec
- Min Detectable Leak at 1000 ppm: 2 x 10-9 atm cc/sec Helium
- Primary Pump Type: SD-301 Rotary Vane Pump
The Varian 959 and 959D Helium Leak detectors are portable, self-contained mass spectrometer helium leak detectors using respectively dry and wet (oil-based) vacuum roughing pumps. The Vacian SD-301 Rotary Vane Pump in the 959 Wet makes the system particularly very robust and reliable.
The Varian SD301 backing pump meets most mechanical vacuum pumping needs, except in clean room applications.
The 959 Leak Detector systems provide clean and automatic leak detection utilizing the Contra-Flow™ vacuum system design that allows testing at high test point pressures. The Variran SD-301 high vacuum mechanical pump in the 959 provides the same functions in situations where the oil-free aspects of the 959D are not required.
A Varian Turbo Pump is used to achieve very high vacuum in the spectrometer tube. SD 301 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.
