The MFT1800 series of multifunction installation testers have been designed 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.

The series is comprised of 3 instruments:

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

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

All instruments are IEC 61010 CAT IV 300 V rated for connection to low voltage systems with no protective device, so can be safly connected anywhere on the system up to the source transformer without risk of damage from large transient spikes.

Visible and audible safety warnings are paramount when testing high energy systems, and the MFT1800 range includes full input protection and safety warnings when a hazardous voltage is present. If live voltages exist on a circuit during insulation or continuity testing, the voltage is displayed on the screen. If this voltage exceeds a safe level, further testing is inhibited and a warning sounds.

Quick to pick up and use, the rotary controls are colour-coded to make range selection easy and fast, also reducing the chance of using the wrong function or range. Additionally, the large clear backlit display uses the patented Megger digital/analogue arc, providing you with indication of fluctuating readings while the dual digital readout shows precise values of key measurements simultaneously with the test parameters, such as the output voltage on insulation testing as well as the resistance value in MΩ.

Due to circumstances beyond our control, Megger has to obsolete certain models from its MFT1800 series. However, this action allows us to focus our efforts on developing new products that better meet your needs and incorporate the latest technologies. The MFT-X1 is our latest product in the multifunction family and can directly replace the obsoleted MFT1800 series instruments and offers more advanced electrical test capability. The MFT1815 and MFT1825 are not affected by this obsolescence and are still available for purchase.

Models affected by the obsoletion:

MFT1835 variants

MFT1845+ variants

Models not affected by the obsoletion:

MFT1815 variants

MFT1825 variants
