ABSTRACT:
A leak detector employing an ion-conducting membrane is disclosed. An oxygen-ion conducting membrane which employs a high vacuum on one side is used to detect very small quantities of oxygen flowing through a minute fissure in a part to be tested for leaks. The oxygen-ion conducting membrane is biased with direct current voltage to drive oxygen-ions through the membrane away from the high vacuum side.
