Edwards APGX-H-NW25 (Stainless Steel) Linear Convection Vacuum Gauge, D02392000
APGX-H NW 25 Overview:
Edwards APGX-H-NW25 (Stainless Steel) Linear Convection Vacuum Gauge has a wide measuring range from 1333 to 3 x 10-4 mbar (1000 to 2.3 x 10-4 Torr). The use of APGX-H-NW16 convection technology ensures accuracy and sensitivity are maintained to the top of the range.
The Edwards APGX-H-NW25 is compact and may be mounted in any orientation, simplifying installation where space is limited. The gauge incorporates a setpoint and two LEDs, which indicate setpoint and gauge status.
The Edwards APGX-H-NW25 uses the constant temperature principle in which the cooling effect of the gas on the filament is overcome by varying the voltage applied, which in turn maintains a constant resistance and keeps the circuit in equilibrium. This voltage is therefore a measure of the pressure in the gauge tube. It should be noted that different gasses have different thermal properties and as such the output of Edwards APGX-H-NW16 is gas dependant.

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.
