Portable Sniffer

The PHD-4™ is a portable, compact leak detector that runs on its own battery for up to four hours. Weighing only 2.6 kg (5.7 lbs) including the battery, it can be taken anywhere. The PHD-4 detects very small leaks in objects that have a slight helium/air pressure inside. It is sensitive to helium concentrations as small as 2 parts per million which equivalent to a leak rate of 5 x 10^-6 atm-cc/sec. This level of sensitivity is far superior to the performance of other means of detecting leaks such as bubble testing.

To accomplish this it relies on Varian’s proprietary and patented Selective Ion Pump Detection (SIPD) technology. Controlled by a microprocessor, the PHD-4 is easy to use with no training required. All tuning and zeroing are handled automatically.

The display can be set to use any of four languages – English, French, German, and Italian.
