This precision test cell is used for dielectric tests, i.e. it determines dissipation factor tand and dielectric constant on test objects of solid insulants such as paper and plastic foils, as well as the specific resistivity. The test cell is equipped with a special shielded measuring electrode (so-called guard ring), which eliminates the partial capacitances, which would influence the test results .This new design is the result of longstanding experience in the field of test cell building and customer feedback. To heat up and to evacuate the test cell, we recommend our temperature controller type RY2-1 and our reliable vacuum pump type RY2-2.
