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.
