The MOA-Ⅱ Arrester resistor DC parameter tester is used to measure the pressure sensitive voltage (U1mA) and leakage current (Id) at 0.75U1mA of zinc oxide varistors.

The tester adopts high frequency and high voltage technology, and organically combines the production, control and measurement of high pressure to form a large closed-loop system, generating high precision constant current and constant voltage source. And has multiple protection, safe and reliable. Throughout the test process, just press the measuring button, the tester will automatically complete the measurement of all items in a few seconds.
The measuring system of the tester has the advantages of digitalization, good stability and high precision. The test result is displayed by three-and-a-half LED digital, and has the memory function, intuitive and clear.
