The Earth tester for all applications - earth stakes and networks, soil resistance, lightning straps and bonds with HF, tower pylons, step potential and more. The MI 3290 Earth Analyzer is a portable, battery or mains powered test instru¬ment with excellent IP protection (IP 54 open case), intended for measure¬ment of earth resistance, specific earth resistance and earth potential of various energized and non-energized objects.

METREL MI3290 Earth Analyser
