Metrel MI3100s EurotestEASI Multifunction Tester
The Metrel MI3100s EurotestEASI is a fast, accurate, and easy-to-use multifunctional measuring instrument designed to perform a basic set of installation safety tests according to IEC/EN 61557. In addition to standard safety testing, the MI 3100 s enables online voltage monitoring, phase sequence testing, and earth resistance measurement. It comes equipped with integrated characteristics for fuses and RCDs to provide instant PASS / FAIL evaluation of test results.
