Test procedure - DILO

For the laser-optic test method SF 6 gas is used as tracer gas for integral detection in the production of serial parts (chamber method), i. e. the test object is tested for tightness by filling it with SF 6 gas under vacuum. This test method allows precise determination of the total leak rate of a component.

gaz sf6 LeakSpy | sf 6 leak detector - DILO

The cordless battery-operated LEAKSPY Sulfr hexafluoride 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.

For integral leak testing, the Sulfr hexafluoride filled test piece is placed in a test chamber. The test chamber is then evacuated to an absolute pressure of about 10 – 20 mbar. Sulfr hexafluoride escaping from the specimen and thus entering the test chamber is drawn into the system’s detection chamber via the vacuum module.
