The Uni-T UT18D is a high-performance voltage and continuity tester specifically engineered for professionals working in demanding electrical environments. Featuring a clear LCD display supplemented by an analog bar graph, this tool provides precise AC/DC voltage measurements across eight distinct levels, from 6V up to 690V. Its robust design is built to withstand the rigors of industrial use while maintaining high accuracy.

This versatile instrument is capable of much more than basic voltage checks; it includes 3-phase voltage and phase sequence testing, RCD leakage protective switch detection, and frequency display. With its CAT IV 600V safety rating and IP65-certified housing, the UT18D is a reliable companion for electricians working in smelting, manufacturing, and complex electrical contracting where harsh conditions are the norm.

Why It Matters

Safety and reliability are critical when troubleshooting high-voltage systems. The UT18D ensures you are never working in the dark, both literally and figuratively, thanks to its built-in flashlight, LCD backlight, and comprehensive safety protections. Its ability to detect polarity and conduct continuity tests with both visual and audible indicators ensures you can diagnose faults quickly and safely.

Technical Specifications

Tradie Pro Tip: Always utilize the 'Self-Inspection' feature before starting your work. By checking that all LCD segments and indicators are functioning, you guarantee that a 'zero' reading actually means no voltage, rather than a faulty display.
