1. Combines a high-hardness alloy steel screwdriver (Lovan steel) with a sensitive digital AC voltage tester. Features a high-torque handle design that allows you to easily loosen or tighten terminal screws, circuit breakers, and outlets while performing electrical testing.
2. Built-in precision smart chip detects AC voltage from 3V up to 500V (50/60Hz). The high-definition LCD dual-color backlit screen displays clear voltage values and status icons, automatically switching backlights and sounding an audible beep during high-voltage detection.
3. Rapidly distinguishes between live and neutral wires based on detected voltage levels. Includes Non-Contact Voltage (NCV) induction mode to safely locate live conductors or break points through wire insulation without direct bare metal contact.
4. The probe shaft is coated with a high-strength protective insulation sleeve to prevent accidental short circuits during deep electrical box operations. Supports emergency live wire detection even when batteries are depleted, displaying a safety warning symbol.
5. Crafted using eco-friendly flame-retardant ABS and TPE soft rubber secondary injection molding for maximum grip, insulation comfort, and impact resistance. Automatically powers down after 3 minutes of inactivity to conserve battery life.
