Helium-Lecksuchgerät
Helium Leak Detector

 

  • High sensitivity
  • Very handy
  • Ergonomically friendly

The helium leak detector PHD-4  operates as Selective Ion Pump Detector (SIPD).

Helium penetrates through a special membrane heated to a specific temperature that allows helium atoms to pass. These are ionised by an ion converter. The detector registers the ion current thus produced and emits a signal whose height is proportional to the He amount detected. The signal amplitude indicates the leak size.
