Vacuum Test Chambers for sf 6 Leak Testing

We manufacture systems of this model range with a chamber volume of 500 l to approx. 20,000 l. We recommend this model range where larger components need to be tested or where integrated gas handling in the test chamber is required. In this case, the test objects are filled with SF 6 in the chamber. Gradual evacuation and filling of the test objects is also possible in order to avoid an inadmissible differential pressure between the test object and chamber.Get price
