UNI-T UT39C Digital Multimeter
The UNI-T UT39C is a compact, hand-held digital multimeter designed for field and bench use. It combines a clear, large LCD readout with a rugged, ergonomic housing and a rotary range switch for fast selection of measurement functions. The meter covers common electrical measurements (AC/DC voltage and current, resistance, capacitance, frequency and temperature) plus diode and continuity checks, making it a practical tool for electricians, HVAC technicians and electronics hobbyists.
UT39C provides manual-range operation with easy-to-use controls, data-hold and a continuity buzzer for quick diagnostics. It includes protection and safety features required for routine electrical work (CAT ratings on many variants) and a sleep/auto-power-off mode to extend battery life. The instrument accepts standard test leads and typically uses a 9V battery (or equivalent) for power.
Built to withstand workshop conditions, the UT39C series often features reinforced insulation, a fold-out stand/holster and drop resistance. Its measurement coverage (including temperature and frequency on + variants) plus simple, reliable operation makes it suitable for maintenance, troubleshooting and installation tasks across automotive, HVACR, residential and industrial contexts.
Features:
- AC/DC voltage and current measurement (wide ranges).
- Resistance, capacitance, frequency and temperature measurement (on + variants).
- Diode test and continuity buzzer.
- Manual ranging with large LCD display (4000-count/4000-3999).
- Data-hold and auto power-off.
- Fold-out stand / holster and robust casing for workshop use.
