Differential pressure decay leak tester CETATEST 825 HP-PR

high-pressurefor valvesfor injection valves

The CETATEST 825 HP-PR in the variant high pressure can be used for leak tests (for example, the housing and seat of injection valves) up to a test pressure of 400 bar using the test mode pressure rise. The area in which the leakage is to be measured is enclosed by a measuring chamber (secondary circuit). Hereby the primary circuit is pressurised with the test pressure (up to 400 bar). The leakage test is performed in the secondary circuit using the differential pressure method. The CETATEST 825 HP-PR can be delivered as 1-channel or 2-channel test device.
