ALVA MFT - Installation Multifunction Tester

Di-LOG ALVA MFT – The Future of Electrical Testing

Introducing the Di-LOG ALVA MFT Installation Multifunction Tester, a next-generation MFT designed to transform electrical testing. Built to meet the latest industry requirements, the ALVA MFT is fully compliant with BS EN 61557 which ensures exceptional safety, precision, and reliability for professional electricians.

Designed for accuracy and ease of use, the ALVA MFT features a vivid full-colour TFT display with interactive controls, allowing users to set pass/fail conditions effortlessly. It supports a full range of RCD types, including AC, A, B, B+, EV and F, making it a versatile solution for modern electrical installations.

The ALVA MFT Installation Multifunction Tester simplifies testing with automated Continuity & Earth Loop Auto Start, accompanied by a secondary display for recorded results. Its intelligent 2/3 wire high-current loop detection eliminates the need for manual selection, automatically identifying whether a 2-wire or 3-wire Loop/PSCC measurement is being conducted.
