The Metrel MI 3250 MicroOhm 10A is a high-accuracy low resistance ohmmeter designed for UK electricians, commissioning engineers and industrial maintenance technicians who need reliable continuity and joint resistance measurements. With a powerful 10 A test current and true 4-wire Kelvin testing, it delivers precise results when testing busbars, breakers, cable joints, transformers and motor windings.
Portable and battery powered, the MI 3250 is ideal for on-site testing during installation, maintenance and fault finding. Automatic bidirectional measurement removes thermal EMF errors, helping engineers trust results even in demanding industrial environments.
How does the MI 3250 improve low-resistance testing on site?
By combining high test current with bidirectional Kelvin measurement, the MI 3250 achieves excellent accuracy down to micro-ohm levels. PASS/FAIL limits and clear visual indicators allow fast decision-making, while onboard memory and PC software support full test reporting without slowing down the job.
