- Theory of working
The original dryair method is pressure decay in which the test part is pressurized and then isolated from the pressure source Because air moves from a highpressure area to a lowpressure area any decrease in pressure indicates the presence of a leak Algorithms then convert pressure changes into an approximation of the leak rate
