NEW - Pre-order the Megger MFT-X1 Multifunction Installation Tester for Feb 2023 Delivery

The Megger MFT-X1 multifunction installation tester covers all test requirements, including EV charge points (when paired with the EVCA210 charge-point adaptor) and domestic photovoltaic systems in low-voltage installations.

Megger have redesigned the MFT and this new tester comes with a host of new features and is designed for use on all single or 3-phase domestic, commercial and industrial electrical installations.

Key innovations include True Loop™, Megger’s most advanced earth loop impedance measurement system, user-configurable auto-sequence RCD testing, automatic volt-drop calculation, stabilised IR test voltage output and – an industry first – plug in Li-ION battery module.

The Megger MFT-X1 can be used with either the Megger Li-ION battery pack, or the AA NiMH or Alkaline battery technologies*. The unique battery pack solution enables the rechargeable 4 Ahr Li-ION pack to be swapped with the AA carrier module, providing the most flexible and fastest battery change solution in the industry. A smart fuel tank chip technology optimises battery status accuracy on the Li-ION pack.
