The Metrel MI 3242 2A Micro Ohmmeter is a compact low-resistance tester designed for UK electricians, electrical maintenance engineers and commissioning technicians who need precise micro-ohm measurements in the field or workshop. Delivering test currents up to 2 A, it allows reliable verification of contact resistance, bonding integrity and conductor continuity on electrical installations and equipment.
With a measurement range from 1 µΩ to 1999 Ω, the MI 3242 is ideal for testing switches, relays, busbars, cable joints, transformers and earthing connections. CAT III 600 V protection and internal safety circuits make it suitable for use in live electrical environments, while its lightweight design supports everyday site work.
How does the MI 3242 improve low-resistance testing on site?
Bidirectional measurement reduces thermal EMF errors, helping electricians achieve stable and repeatable results even on very low resistance values. Built-in PASS/FAIL limits with clear red and green indicators allow fast decision-making during inspections, fault finding and maintenance routines.
The internal battery supports hundreds of measurements per charge, and onboard memory stores up to 1500 results with timestamps. Test data can be downloaded using HVLink PRO software, supporting professional reporting, record keeping and compliance documentation.
