Pressure Decay is one of the oldest but surest methods of leak testing. In the most simple pressure decay leak testers, the part is filled to the test pressure, the fill valve is closed and then the pressure is monitored. If the pressure loss is within the specification, the part is treated as a good part. Today there are more sophisticated options and functions available to pressure decay instruments that allow them to be a steady work horse in the leak testing world. Air Pressure Decay is well suited for many applications. Gauge pressure decay is often a first choice when the project budget is limited. Pressure decay works best when the decay due to the leak is large compared to other influences. ATEQ has a number of pressure decay instruments in our product line. If pressure decay is unable to meet your requirements for leak rate or production rate, then ATEQ also has differential pressure decay leak testers for more accurate testing. Let us be your consultant and help you balance faster leak testing with quality measurements.

Mass Flow Test:
ATEQ's mass flow test instruments are available for testing in both pressure and vacuum. Available mass flow test technologies include mass flow and continuous mass flow.

Calibration equipment for your Pressure Decay Leak Tester:
ATEQ makes it easy to validate your leak test, to calibrate any leak or flow orifices and to conduct leak or flow rate studies. Our portable leak and flow calibrator can be taken to your production line and it can be used in your lab. Traceable and simple to use - anywhere.
