What is a Leak Test? Leak tests, on the other hand, are performed to detect and quantify leaks within a system. Rather than merely identifying weak points, leak tests aim to measure the leak rate or the amount of fluid that escapes from the system over a given period. The Concept of Pressure Decay. In leak testing, pressure decay is a commonly .TEST TYPE : Pressure, Vacuum; TEST RANGE : Pressure(0.1~1.5 bar) / Vacuum(0.1~0.8 bar) ACCURACY : 0.02 bar; WORKING PRESSURE : 0.5~0.6 MPa; DISPLAY : 10.2″ TFT Color LCD with Resistive; COMMUNICATION PORT : RS232C, Start(Input) Signal, Pass(Output) Signal; OPTION : LTE Expansion, Auto Start System, Washer Hose Test System, CH Air FilterLeak tester QualiLeak-M2 utilizes compressed air as its power source and employs a high-precision electronic pressure sensor for measurement.
