For testing a wide range of different cylinders and valves, HAINZL has developed a universal test stand that enables a broad test scope: function test, leakage test, static pressure test, friction test and much more. All tests are performed in a closed test cell to protect the user from escaping media. Working on the tester in the test cell while it is running is possible for pressures up to 100 bar.
