The industrial PC controlled CETATEST 825 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. Hereby the pressures in the test part volume and in a leak-tight reference volume are compared. Leak tests at very low test pressures can be carried out with the test device variant CETATEST 825 LP (Low Pressure). The special variant CETATEST 825 HP-PR (high-pressure pressure-rise) is suitable for high-pressure leak testing of products that can be filled on one side. The integrated 7-inch touch-screen with an intuitive operable graphical user interface makes it possible to display a wide range of information (for example, measurement curves, histograms). Operation is possible both via the touch-screen and via a dual-jog dial. Separate start / stop buttons ensure operating safety even in harsh industrial environments. The memory stores more than 1 million measurement results and 256 test programs.
