The Agilent Technologies / Varian Models 959 and 959D are portable, self-contained mass spectrometer helium leak detectors using respectively dry and wet (oil-based) vacuum roughing pumps. The dry pump in the 959D makes the system particularly useful in clean room environments where a wet, oil-based pump cannot be tolerated. The pumps have identical operating characteristics, although the 959D is somewhat heavier. The wet pump meets most mechanical vacuum pumping needs, except in clean room applications.
The systems provide clean and automatic leak detection utilizing the Contra-Flow™ vacuum system design that allows testing at high test point pressures. The 959D provides a dry, oil-free vacuum pumping system. The TriScroll dry roughing pump evacuates the test port to the appropriate transfer pressure and provides ultra-clean system roughing and backing functions. The DS-302 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 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.

Our highly trained technicians have years of experience and guarantee the highest quality service.
We operate at our own full service repair facility in Clifton, NJ. We have invested in state-of-the-art equipment including; complete line of decontamination, cleaning, drying, balancing, vibration analysis and software to minimize failures. Our in-house machine shop is capable of machining various components, prototypes and housing conversions as needed.
We support all major manufacturers including Pfeiffer Vacuum, Alcatel / Adixen, Edwards Vacuum, Varian, Oerlikon / Leybod Vacuum, Vacuubrand, and Agilent Technologies.
Repair Steps
Every pump and instrument is extensively tested for 48 hours. During our final tests, we monitor total pressure, temperature, vibration and noise level utilizing newest testing technologies and techniques specified by OEM. Upon request, we can provide our customers with a pump down graph. Call us for your free repair estimate at 1-973-249-0854.
