The Agilent Technologies Internal Filter Kit is designed to be used with the PHD 4 Portable Helium Leak Detector.
The Agilent Varian PHD-4 Portable Helium Leak Detector permits fully automatic detection of concentrations of helium down to a lower limit of 2 parts for million (ppm). The value of the leak is shown in real time on the graphic display on the front panel. The instrument, which emits an acoustic signal proportional to the concentration of helium detected, incorporates a self-test program, making it possible to carry out any type of operation using the soft-keys on the front control panel. The operator can use the straps provided to carry the unit and locate leaks using the extensible probe.
The system to be tested is filled with a mixture of helium/air. The probe is passed over areas considered to be critical and, via a sampling pump, the mix of gases around the areas examined is sampled and piped towards the internal sensor. The sensor consists of a pressure detector and of a heated quartz capillary which is highly permeable to the molecules of helium, while permeability for all other atmospheric gases is negligible. While the atmospheric gases are vented to the outside, the molecules of helium reach the pressure detector. The electric signal proportional to the partial pressure of the helium taken from the detector, is processed by the microprocessor of the central unit. This permits direct readout of the concentration of helium on the display.

- Diaphragm Dry Pumps
A & J Vacuum Services provides repair service for all types of High Vacuum equipment. We perform Turbomolecular Pump repair, Turbo Pump Repair, Dry Pump repair, Vacuum Pump repair, Mass Spectrometer repair, Rotary Vane Pump repair, Vacuum Booster repair, and Leak detector repair. 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
- Full incoming inspection and run up time check, vibration check, drive inspection.
- Full disassembly, decontamination and cleaning.
- Pump is balanced utilizing state-of-the-art equipment from the world leader in equipment balancing and analysis to reduce noise and vibrations and extend bearings life.
- Assembly and replacement of all necessary parts such as shafts, bushings, bearings, sleeves, O-rings, gaskets, seals, wicks, etc. Only parts that meet or surpass OEM specifications are used to ensure dependable highest quality service and long pump life.
- Final test and leak check. The pump in fully assembled condition is checked for vacuum seal. Leak test to 1 x 10-9 Mbar l/s. Vibrations are analyzed and test data is digitally recorded.
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.
