UNI-T Multimeter UT 139C

The UT139C measures AC/DC voltage, AC/DC current, resistance, capacitance, frequency, and temperature with high accuracy. In addition, it includes continuity and diode testing functions, allowing users to diagnose electrical circuits and electronic components efficiently. The True RMS technology ensures accurate readings when measuring non-linear loads and complex electrical signals commonly found in modern electrical systems.

Professionals use the UNI-T UT139C to troubleshoot electrical equipment, inspect power distribution systems, test motors, verify wiring installations, and perform preventive maintenance tasks. As a result, technicians can identify faults quickly, improve system reliability, and reduce equipment downtime.

The multimeter features a large backlit LCD display that provides clear visibility in both bright and low-light working environments. Furthermore, the device includes NCV (Non-Contact Voltage) detection, helping users identify live voltage safely without direct contact. This feature improves workplace safety and simplifies electrical inspections.

The ergonomic design ensures comfortable handling during extended use, while the durable construction supports demanding industrial environments. In addition, the meter includes practical functions such as data hold, auto-ranging, MAX/MIN recording, and auto power-off for greater convenience and efficiency.
