A method and apparatus for leak testing of liquid and non-liquid filled rigid and semi-rigid nonporous containers wherein a container is enclosed in a conforming test chamber and subjected to vacuum while the pressure within the chamber is monitored by an absolute pressure transducer, alone or in combination with a second differential transducer, to determine if leaks are present in the container and wherein the test apparatus or system remains under low pressure or vacuum conditions while leak tests are not actively in progress such that the system is maintained at an at-rest low vacuum condition to minimize pressure sensor drift and to eliminate build-up of vapors or gases within the apparatus or test system between tests that may hinder the speed and sensitivity of the leak tests.
