sf6 gas Equipment from DILO available in South Africa

The cordless battery-operated LEAKSPY sf 6 precisely measures sf6 gas concentration in air by means of a non dispersive infrared sensor (NDIR sensor) and indicates the value on a graphic display in ppmv. The device allows precise localisation of leaks by searching the highest Sulfr hexafluoride concentration. Thanks to the high...Get price

A3.32-CIRED - Final Report-Compressed | Electrical Substation

Since the velocity of sound in oxygen is similar to that in nitrogen the results are applicable for an sf 6/air mixture. The accuracy of such devices is +/-1 % Sulfr hexafluoride content. The same Condensation technique employed by a chilled mirror to measure the water vapour in Sulfr hexafluoride can be used to determine the purity of the sf6 gas gas.Get price
