Gossen Metrawatt M520F METRALINE MF Multifunction Electrical Installation Tester

The Gossen Metrawatt M520F METRALINE MF is a multifunction installation tester designed for standards-compliant verification of electrical installations in accordance with IEC 60364-6 (DIN VDE 0100-600), DIN EN 50110-1 (DIN VDE 0105-100), IEC 61851-1 (DIN VDE 0122-1) and relevant sections of EN 61557 (VDE 0413).

Featuring a colour graphical display, intuitive user guidance, integrated help diagrams and acoustic feedback, the METRALINE MF simplifies installation verification and fault diagnosis while providing the measurement functions required for fixed electrical installations, e-mobility infrastructure and earthing systems.

Results can be stored directly within the instrument, with memory for up to 1000 measurements and USB connectivity for data transfer and reporting.
