Reliable Electrical Diagnostics - Real-time voltage detection from 12V to 300V across multiple scenarios. The LCD interface provides break point localization and clear differentiation between neutral and live wires for quick, accurate readings. Contactless AC Detection for Safe Testing - Non-contact voltage (NCV) sensor technology enhances electrician safety. Dual audio-visual alerts confirm voltage presence, helping to prevent accidental contact and oversights during checks. Compact and Portable Design - Small, lightweight, and easy to handle. This portable tester is simple to carry and store, making it suitable for use across different electrical systems without sacrificing performance. Reliable Testing Solution - Variable-frequency buzzer feedback, insulation safe technology, and live circuit prevention support safe operation. Intelligent auto-voltage recognition adapts to diverse user scenarios for reliable results. Use scenarios - Residential wiring and appliance installation: verify outlet voltage, locate break points, and distinguish neutral from live wires before or during installations and repairs. - Commercial and industrial environments: quickly check panels, control cabinets, and equipment wiring to confirm voltage status prior to maintenance. - Field service and inspections: perform fast, non-contact voltage checks on cables and devices to ensure safety before disassembly or live work.
