Isolation Tester UIP

isoprueferThe devices of the UIP (Union Isolations Prüfer) isolation tester series are used to test the pore-free condition of corrosion protection coatings of pipes, vessels or plant system parts. The battery-powered device generates test voltages between 5 kV and 30 kV, which are applied to the grounded test object via test electrodes. The location of a defect is signalized by a spark-over with an additional audible warning.
