UNI-T UT123D Digital Multimeter – NCV Auto Range AC/DC Voltage Current Resistance

UNI-T UT123D Smart Digital Multimeter | Auto Smart Mode NCV Tester

Compact Auto-Ranging Multimeter for Home DIY, Electrical Service and Maintenance in Sri Lanka

The UNI-T UT123D is an intelligent smart digital multimeter featuring automatic function detection and one-button operation, perfect for electricians, home DIY users and maintenance technicians across Sri Lanka. With True RMS AC/DC voltage up to 600V, 10A AC/DC current, 40MΩ resistance, 4000μF capacitance, NCV non-contact voltage detection and continuity testing, this pocket-sized 130g meter eliminates manual range selection and function switching. Its EBTN backlit display and built-in flashlight make it ideal for working inside dark distribution boards and meter cabinets.

The UT123D automatically identifies AC/DC voltage, resistance, diode and continuity without mode changes, while manual button access provides capacitance, current and frequency measurement. Smart NCV detection with color-coded LED indicators (green=weak, red=strong electric field) and acousto-optic alarms enhance safety during initial circuit assessment. CAT III 600V safety rating, auto power-off and low battery indication ensure reliable performance for household troubleshooting, appliance repair and basic commercial electrical work throughout Colombo, Gampaha and beyond.
