Our flagship model taking the NZ market by storm, the sharply-priced MIT525 is a stunning and fully-featured compact, light 5 kV insulation resistance tester for the diagnostic testing and maintenance of high voltage electrical equipment. As well as measuring insulation resistance to 10 TΩ, the Cat IV-rated MIT525 also offers various diagnostic tests such as Polarisation index, Dielectric Absorption Ratio, Step Voltage, Dielectric discharge and ramp testing. True of all models in this range, its superb noise immunity offers contractors the highest levels of confidence in the harshest of substation electrical environments.

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.
