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.
