UNI-T UT39C Digital Multimeter
UNI-T UT39C Digital Multimeter 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.
