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.
