Multi-function Digital Socket Tester

FEATURES GLOBAL SOCKET COMPATIBILITY: Tests all U.S., European, and British standard outlets with automatic detection. The intelligent design eliminates guesswork when checking foreign appliances or verifying wiring in international properties. Unlike single-standard testers, this adapts instantly to any socket configuration you encounter. BATTERY-FREE OPERATION: Powered directly from the tested outlet for always-ready functionality. The energy-efficient system draws minimal current while providing clear diagnostics, ensuring you'll never face dead batteries during critical electrical inspections. Simply plug in for instant voltage readings and safety checks. DUAL-COLOR VISUAL ALERTS: Features a high-definition LCD with color-coded backlighting (green for safe, red for faults). This intuitive system provides immediate visual confirmation of wiring issues like reversed polarity or open ground, even in low-light conditions where traditional testers fail.
