Reliable leak testing with compressed air
The CETATEST 820 uses compressed air as the test medium and is suitable for directly fillable products and for test pressures from -1 bar to 10 bar. The use of the differential pressure method enables the reliable measurement of low pressure losses or small leakage rates. This is particularly important in sectors such as the automotive industry, medical technology and the packaging industry, where the highest quality standards apply. The CETATEST 820 has a differential pressure measuring range of ±500.0 Pa with an internal resolution of 0.01 Pa.
The core of the CETATEST 820 is a real-time system which, in combination with a highresolution 24-bit A/D converter, guarantees fast and precise measurement data evaluation.
The device offers a variety of measuring result units, including Pa, psi, Pa/s, psi/s, ml/min, mbar l/s, mmHg, mmWs.
In addition to the test method of pressure decay testing, the CETATEST 820 is equipped as standard with helpful additional functions such as nominal pressure optimisation, prefilling, pulsing and smooth filling. A freely programmable pneumatic control output is available as an option. This can be used, for example, to switch external pneumatically actuated changeover valves that control a stamping device or enable measuring point changeover.
The compact 3 U tester is operated via a 7-inch color touchscreen and separate start/stop buttons.
The CETATEST 820 is equipped with a digital I/O interface, RS-232, USB (host) and Ethernet as standard. Profinet protocol activation for external gateways recommended by CETA is available as an option. The supply voltage is 24 VDC. An UL-certified power supply unit is available as an option. This makes the test device suitable for integration into automated production lines.
The device has a storage capacity for 100,000 measurement results and 64 individually configurable test programs with alphanumeric program names. Test programs can be exported and imported via communication interfaces or an USB storage medium. The CETATEST 820 also offers result statistics, a cycle counter, user administration and the export of test parameters, measurement curves and measurement series to USB storage media.
Software for advanced analysis
The CETA Soft 2G application software is available free of charge and enable measurement series management and a variety of graphical presentations (measurement curves, histograms) for a detailed analysis of the test results.
Warranty and DAkkS-accredited calibration
All CETA test devices, including the CETATEST 820, and calibration standards are supplied with an internationally recognized DAkkS-accredited calibration certificate in accordance with DIN EN ISO/IEC 17025 as standard and at no extra charge (DAkkS = German Accreditation Body).
This calibration fulfills the requirements of the international automotive standard IATF 16949.
CETA grants a standard 3-year warranty on test devices with annual maintenance, with an optional extension to 5 years.
Cost-efficient quality product
The extensive range of functions, proven and precise measurement technology, 3-year warranty and DAkkS-accredited calibration are interesting added values of the cost-efficient CETATEST 820, which is priced at less than €10,000. The CETATEST 820 will be available from the 3rd quarter of 2025.
