counterflow helium leak detector

mass spectrometer leak detector in which the tracer gas (helium or hydrogen) enters through the backing line into the outlet port of the high vacuum pump and the partial pressure of the tracer gas is measured on the high vacuum side of this pump

maseni spektrometar, kod koga ispitni gas (helijum ili vodonik) kroz povratnu liniju ulazi u izlazni priključak visokovakuumske pumpe, a parcijalni pritisak ispitnog gasa se meri na strani visokovakuumske pumpe
