Uni-T UT620C+ Portable Resistance Meter | Micro-ohm

The Uni-T UT620C+ delivers exceptional precision for professionals who demand reliable resistance measurements in challenging industrial environments. This advanced portable resistance meter combines cutting-edge technology with practical design, making it the ideal choice for maintenance teams working with large transformers, motors, and high-power electrical equipment.

Engineered for accuracy, the UT620C+ measures resistance across an impressive range from 1µΩ to 200mΩ with outstanding 0.5% basic accuracy. This micro-ohm meter eliminates guesswork when testing critical connections, detecting loose bolts, corroded joints, and degraded conductors that could lead to costly equipment failures. The device’s four-wire Kelvin measurement technique ensures precise readings by compensating for test lead resistance, delivering consistent results even in noisy industrial environments.

What sets this resistance testing device apart is its robust construction and user-friendly operation. The large, backlit LCD display remains clearly visible in poorly lit maintenance areas, while the intuitive interface allows technicians to quickly configure test parameters. The instrument’s automatic range selection speeds up testing procedures, whilst manual range override provides complete control when needed.

For maintenance professionals managing extensive equipment portfolios, the UT620C+ offers remarkable versatility. Its wide measurement range handles everything from high-current busbar connections to delicate relay contacts. The device excels in power plant maintenance, where monitoring transformer winding resistance prevents catastrophic failures. Mining operations benefit from its ability to test heavy machinery connections under harsh conditions.

The portable design doesn’t compromise on functionality. Built-in data logging capabilities store up to 100 measurements, enabling comprehensive maintenance records without additional paperwork. The USB interface facilitates easy data transfer to maintenance management systems, streamlining compliance reporting and trend analysis.

Battery life extends through multiple shifts, ensuring uninterrupted testing during critical maintenance windows. The rugged housing withstands drops and vibration common in industrial settings, while the protective case organises test leads and accessories for efficient field deployment.

This micro-ohmmeter addresses common maintenance challenges that cause unplanned downtime. By identifying resistance increases before they become failures, maintenance teams can schedule repairs during planned outages, significantly reducing operational costs. The device’s precision helps distinguish between acceptable connection resistance and deteriorating conditions requiring immediate attention.

For procurement teams evaluating resistance measurement solutions, the UT620C+ represents excellent value through its combination of accuracy, durability, and comprehensive features. Its proven performance in demanding applications makes it a trusted choice for facilities where equipment reliability directly impacts productivity and safety.

Choose the Uni-T UT620C+ when precision matters and reliability cannot be compromised.
