  • sf 6 Leak Detection wika

    The importance of monitoring SF6 gas leaks and emissions Although SF 6 is non-toxic, any escaped gas can displace oxygen in the air and lead to asphyxiation in closed spaces. It is also a potent greenhouse gas – 23,900 times more effective than carbon dioxide at trapping infrared radiation in the atmosphere.

  • SF6 LeakSpy | SF6 leak detector

    The cordless battery-operated LEAKSPY SF6 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.
