The Cat IV- rated MIT515 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 and rotating plant. The tough case is small and lighter than its predecessor making it easy to carry and store.

Now equipped with lithium ion fast rechargeable batteries, 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.
