- Min Detectable Leak at 1000 ppm: 2 x 10-9 atm cc/sec helium
- Primary Pump Type: SD-301 Rotary Vane Pump
Varian 959 Helium Leak Detector, Mass Spectrometer with SD-301 Rotary Vane Pump, Mobile Cart, 115 V, D9593500TM120
Varian 959 Overview:
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 Varian 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.
The Varian 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.
The basic pump components are:
Test port that connects the leak detector to the unit under test or to an associated vacuum system
High vacuum turbo pump
Spectrometer tube
959 Wet: SD-301 oil-based mechanical vacuum pump
Leak detector electronics
Front control panels, rear I/O, and power panel on cart
Operation of this Varian 959 detector is performed using primary controls located on the front of the leak detector and secondary controls located behind a locking access door, also at the front of the leak detector. The front view is shown in Figure 1-1 and Figure 1-2. The 959 leak detector electronics operate the spectrometer assembly, control the high vacuum pump, control the valve block, and provide leak rate and system status information to the operator through bar graph and LED indicators on the front panel, through audio, or through an optional meter or chart recorder.
