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. COMPREHENSIVE SAFETY TESTING: Performs complete diagnostics including RCD (residual-current device) detection and leakage current testing. The advanced circuitry identifies dangerous wiring faults that could lead to equipment damage or electrical fires, going beyond basic socket testers that only check simple connections. PRECISE VOLTAGE MEASUREMENT: Displays exact AC voltage (90-250V) and frequency (45-65Hz) on its crisp LCD screen. Monitor power quality to protect sensitive electronics from voltage fluctuations, with accuracy comparable to professional multimeters in a compact, user-friendly package. SPEC Size: 58×62×65mm Voltage Range: 90-250V AC Frequency: 45-65Hz Standards: U.S./European/British PACKAGE INCLUDES 1 x Digital Socket Tester NOTES For indoor use only – not rated for wet locations Always verify operation on known good outlet first Red backlight indicates wiring faults requiring correction
