How to Detect IR SF6 LeakSpy in high electrical switchgear

The cordless battery-operated SF 6 LeakSpy precisely measures SF 6 concentration in air by means of a non dispersive infrared sensor (NDIR sensor) and indicates the value on a graphic display in ppm v. The device allows precise localisation of leaks by searching the highest SF 6 concentration. Thanks to the high accuracy and the low detection limit it is possible to carry out integral measurements as well as measurements for determination of leakage rates.
