Megger MFT1800-MULTIFUNCTION INSTALLATION TESTER

The MFT1800 series is a range of 3 instruments for testing low-voltage electrical installations to the requirements of all IEC 60364-derived standards. They provide all the tests required to complete the necessary electrical certification for industrial, commercial, and domestic fixed wiring installations.

MFT1815 – The entry-level tester is offering CAT IV safety, 200 mA continuity, 2-wire non-trip loop testing with resistance and fault current display, frequency measurement, and the market’s largest, brightest and clearest display.

MFT1825 – The most popular of the range of testers offering all the benefits of the MFT1815, plus 3-pole and 2-pole earth electrode testing, 15 mA continuity testing, auto RCD testing, phase rotation, programmable and 3-phase RCD testing, and current measurement with the optional clamp.

MFT1835 – This advanced model bring the added benefit of Type B RCD testing, 3-pole earth electrode testing with attached rod technique, and stateless testing to a downloading and rechargeable instrument.
