UNI-T UT620C+ Digital Micro Ohm Meter – DC Low Resistance Tester

UNI-T UT620C+ Micro Ohm Meter in Sri Lanka

Portable Digital Micro Ohmmeter for DC Low Resistance Testing

The UNI-T UT620C+ Micro Ohm Meter is a portable four-wire DC low resistance tester designed for accurate resistance measurement from micro-ohm to kilohm levels. It is suitable for testing wires, switches, connectors, contactors, fuses, coils, transformer windings, metal rivets and other low-resistance electrical connections.

With 1µΩ-level micro-ohm measurement, automatic ranging and a maximum test current of 1A, the UT620C+ helps technicians perform reliable contact-resistance and winding-resistance checks. Its 500-record data storage and USB Type-C interface support convenient measurement review, record keeping and data export through compatible PC software.
