Offering CAT IV, Megger MIT515 5-kV Insulation Resistance Tester is the simplest of Megger's new range of small light 5 kV insulation resistance testers for the testing and maintenance of high voltage electrical equipment. Enclosed in a tough case it is both smaller and lighter than its predecessor making it even easier to carry and store.

Now equipped with lithium ion fast rechargeable batteries, the Megger MIT515 5-kV Insulation Resistance Tester 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.
