Advanced multifunction device for verification of electric safety of private and industrial electric systems


MacrotestG1 fully takes advantage of the touch-screen technology developed for MacrotestG3 and, hence, of all its settings, but its application range is for measuring earth resistance by voltammetric method, also with optional clamp T2100 and, finally, for continuity measurement of protective conductors. Cutting-edge management of measurement with indication, at the end of each safety test, of compliance or non-compliance with requirements with simple symbols OK and NOT OK.
