Megger MIT230HD Insulation & Continuity Tester, 250 V Min, 1 kV Max, 1000 mΩ CAT III, RSCAL

Check that the electrical resistance of your device is up to scratch with this insulation tester from Megger. It measures insulation up to 1000MΩ at voltages of 250V, 500V and 1000V. The handy battery-powered unit also reads the continuity of your system to detect any breaks in the circuit. This particular test has an autostart feature, leaving your hands free to hold the test probes. You can review your results on the robust LCD for easy monitoring. As this display comes with an analogue pointer, you can pinpoint the exact conditions of your circuit.

• Auto power-down helps conserve battery life

• Avionics

This device measures continuity between 0.01Ω and 100MΩ, so you can reliably detect a broad range of conditions in your circuit. Testing is done at 200mA to meet international standards.

Yes, its built-in voltmeter kicks in automatically when it senses voltage greater than 25V to give you instant readings.
