Leak Tester CETATEST 525

The industrial PC controlled CETATEST 525 with 7" color touch screen and dual jog dial is a fully automatic leak tester for the detection of leaking parts within the cycle time of the production process. The differential pressure method is used here. This is based on comparing the pressures in the test part volume and in a leak-tight reference volume.


The use of fast-switching solenoid valves in combination with a very small internal measuring circuit volume makes the CETATEST 525 particularly suitable for very short test processes.


The CETATEST 525 is available in two variants:

The variant "Pressure decay test" is suitable for leak testing of the smallest test parts with a high cycle rate.

The version "Sealed components with high-resolution" enables the testing of test parts that cannot be filled internally (sealed) and the detection of the smallest test volume ratios (0.03 ml < ΔV < 1.0 ml). 


More than one million measurement results can be stored in the test device and over 256 individually parameterisable test programs with alphanumeric designation are available.

Additional pressure ranges On request


All leak, mass flow and flow testers as well as pressure manometers and calibration standards (test leaks, master jets) are supplied with DAkkS-accredited and internationally recognized calibration certificate (compliant with DIN EN ISO/IEC 17025) as standard and at no extra charge on initial delivery.

Prerequisite: The pressure and flow ranges are within the accredited scope of services of the DAkkS-accredited calibration laboratory of CETA Testsysteme GmbH.
