Test Principle of Differential-pressure Method . Differential pressure method has no selectivity to test gas. It is low in test cost and high in test efficiency. The most salient feature of this method is that the gas is pure in the test environment.A second drawback of the absolute pressure decay method is the effect of the Adiabatic Process; when the item is brought up to test pressure there will be an increase in temperature. Subsequent heat dissipation may lead to a pressure decrease during the test phase, which the instrument will incorrectly perceive as a leak. The Differential Method
