UNI-T 690V AC/DC Voltage Line Tester

AC/DC Voltage Testing: Measures voltages from 12V to 690V with automatic range selection

Visual Indicators: Bright LED indicators display voltage ranges in 7 steps: 12V, 24V, 50V, 120V, 230V, 400V, and 690V

Polarity Indication: Clearly identifies the polarity of DC voltage

Phase Rotation Test: Determines the phase sequence in three-phase systems (L1, L2, L3)

Single-Pole Voltage Detection: Detects live wire with one test probe

Continuity Test: With visual (LED) and audible buzzer feedback for fast circuit checks

Work Light: Integrated LED torch for low-light environments

Auto Power-Off: Conserves battery when not in use

Waterproof and Dustproof: IP65-rated for use in harsh conditions

Safety Rated: CAT IV 600V / CAT III 690V – ideal for high-voltage environments
