VARIAN PHD - 4 VS Leak Detector

Description

VARIAN PHD - 4 VS Leak Detector.
PHD-4 Sniffer
The PHD-4 sniffer leak detector is a lightweight and rugged sniffer, sensitive to helium concentrations as low as 2 ppm – equivalent to a leak rate of 5 x 10–6 atm-cc/sec, far superior to bubble-testing, dye penetrants, and pressure decay. The sensitivity of the PHD-4 is enabled by Agilent’s proprietary and patented SIPD (Selective Ion Pump Detection) technology.
With automatic startup, self-test and calibration, the PHD-4 is easy to use with minimal training required. It is powered by a rechargeable battery pack with a 4-hour runtime.
The PHD-4 is a complete battery powered portable helium leak device. The battery pack can be recharged only and exclusively inside the PHD-4, connecting the Agilent SR03.702888 power supply unit to the power supply port 3 (Power Supply connector). The PHD-4 portable 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. Since the sniffer is microprocessor controlled it is easy to use and no training is required. 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.
