Flow Tester CETATEST 925
The CETA flow testers can be used to measure volume flow rates using compressed air as test medium. The measuring method uses the fact that the pressure difference between two measuring points in a laminar flow is directly proportional to the volume flow. By using suitable laminar flow elements, a wide range of flow rates can be measured.
The special variant CETATEST 925 LP (Low Pressure) is particularly suitable for measuring large volume flows at very low test pressures (up to 10 mbar).
The integrated 7-inch touch screen with intuitive, user interface provides a wide range of information (e.g. measurement curve display, histograms). The test device can be operated via touch screen and dual jog dial. Separate start/stop buttons ensure operating safety even in harsh industrial environments.
The memory capacity is sufficient for more than 1 million measured values and 256 test programs.
