Leak Tester Application Software CETA Soft 2G for free! Leak Tester CETATEST 525 The CETATEST 525 with differential pressure sensor is a full automatically working leak tester for the detection of untight 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 different types: The type “pressure decay measurement PD” can be used for leak tests of very small test parts in high speed production. The configuration “sealed components - high resolution SC HR” can be used for test parts which cannot be filled, so called “sealed components”. It is possible to detect very small ratios of test part volumes (0.03 ml < ΔV < 1.0 ml).
