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 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).
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.

| Pressure sensors | Differential pressure sensor, gauge pressure sensor |
| Pressure ranges | -1 bar, 200 mbar, 1 bar, 6 bar, negative and positive gauge pressure ranges can be combined (e.g. -1 bar / +1bar) |
| Measurement ranges | ± 500.0 Pa / ± 5,000 Pa (internal resolution: effectively 0.01 Pa) |
| Variants | Pressure decay measurement PD / Sealed components - high resolution SC HR |
| Dimensions | W x H x D: 367 mm x 183 mm (4 U) x 435 mm |
| Interfaces | I/O interface for start / stop / reset, program selection, device status, system errors, test results (pass / fail) |
| RS-232, USB (host), Ethernet and optional interfaces allow additional functions like parameterisation, measurement results, detailed information in real time (e.g. measurement curve), failure messages | |
| Optional interfaces: Profibus DP, Profinet, EtherCAT or USB (Slave) | |
| The CETATEST 525 is fully interface compatible with the CETATEST 515 and well prepared for Industry 4.0 requirements | |
| Typical applications | Tests of micro switches, sensors, relays, valves, watches |
| Additional pressure ranges | On request |
Remark
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.
