MI 3155 EurotestXD Insulation Resistance Tester

Metrel MI 3155 EurotestXD Installation Tester for testing in industry

Metrel MI 3155 has been designed for electrical power systems, industrial systems, building facility management and special installations/locations.

Metrel MI 3155 EurotestXD is the newest flagship of Metrel’s most advanced line of multi-functional measuring instruments and is designed specifically for testing in industry. What differentiates this instrument from the rest is its ergonomic design and an intuitive user interface, encompassing a memory organiser and fully programmable AUTO SEQUENCEs, managed through a large colour touch-screen display.

Fully compliant with functionality standards (e.g. IEC/EN 61557) and other reference standards for testing (e.g. IEC/EN/HD 60364-4-41,...) as is required for any instrument that performs TRMS current measurements, RCD tests, line and loop impedance tests with 3 (and 4) wires and earth resistance measurements. Besides those, the instrument supports a wide range of tests and measuring functions, including on-line voltage monitoring, phase sequence testing, varistor testing, PI/DAR calculation, luminance measurement, discharge time testing, ISFL measurements, IMD tests as well as functional and visual inspections.
