Megger MIT525 - 5 KV INSULATION TESTER
Model No :
MIT 525
Part Code :
1001-939

Overview

The MIT525 is compact, light 5 kV insulation resistance tester for the diagnostic testing and maintenance of high voltage electrical equipment. It is both smaller and lighter than its predecessor, making it even easier to carry and store.
The instrument has a large, clear, easy-to-read display, making it equally suitable for use in both bright sunlight and poorly lit environments. Information displayed includes resistance, voltage, leakage current, capacitance, battery status and time constant. In addition, the elapsed time of the test is displayed constantly removing the need for separate timer.
