SF6 LeakCheck P1:p leak detector

Transportable SF6 Leak Detection

SF6 LeakCheck P1:p with award winning Negative Ion Capture (NIC) technology is designed for the location, leak testing, and measurement of SF6 leaks in high voltage electrical switchgear.

The revolutionary SF6 leak detector rapidly detects leaks down to 1 x 10-8 ml/sec, with a response and clear down of less than 1 second.

The instrument’s award winning Negative Ion Capture (NIC) technology with non-radioactive source eliminates problems of registration, storage, and transportation.

The LeakCheck P1:p SF6 leak detector is unaffected by large leaks and will continue to remain uncontaminated even after exposure to 100% SF6 gas.

Ion Science also offers a leading range of leak detectors:
