Your choice of leak test method and technology can make a substantial difference in the results of your test, affecting your throughput, repeatability, product quality, and cost.
Pressure Decay leak testing is a popular leak test method used by manufacturers across North America. While traditional Absolute Pressure Decay (integrated with a 24 bit A-D circuit) proves effective for most applications, when manufacturers require better resolution and quicker cycle times Differential Pressure (DP) Decay is becoming a popular alternative. DP offers high-sensitivity, low resolution testing, allowing manufacturers to identify problems faster, increase Gage R&R, and shorten test times.
