Agilent PHD-4 Portable Helium Leak Detector
The PHD-4 sniffer leak detector is able to detect very small leaks in objects that have a slight helium/air pressure inside.
The lightweight and rugged sniffer is sensitive to helium concentrations as small as 2 ppm- equivalent to a leak rate of 5x 10-6 atm-cc/sec, far superior to the performance by other means of detecting leaks, such as bubble-testing. The PHD-4 sensitivity relies on Agilent’s proprietary and patented SIPD (Selective Ion Pump Detection) technology. Since it is 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).
The PHD-4 weighs only 2,6 Kg (5.7 lbs) including the battery
Wide range of uses: replaces or can be used with existing methods such as bubble test or pressure decay
State-of-the-art microprocessor control allows great simplicity of operation
Fully automatic start-up
Ready for test in less than 3 minutes
Excellent selectivity for helium allows you to read helium leaks and ignore all other gases
Helium sensitivity can be adjusted as required to minimize test costs and helium consumption
Can operate either on battery power or connected to an outlet
