The Digital Voltage Detector is designed for versatility across multiple working conditions:
Electrical Maintenance: Quickly determine whether cables, sockets, or switches carry voltage before repair.
Industrial Inspection: Ideal for production lines, machinery maintenance, and equipment installation.
Construction and HVAC Testing: Verify live wires during system setup or renovation to ensure safe operation.
Home Improvement & DIY: Perfect for homeowners who regularly check appliances, outlets, or extension cords for faults.
Educational Laboratories: Demonstrate safe voltage detection for training electrical students or apprentices.
Certified Quality: Manufactured under strict electrical safety standards with multi-layer insulation for protection.
Over-Voltage Protection: Ensures the tester remains safe even when accidentally exposed to higher voltages.
Built for Long Service: Durable ABS material resists drops and abrasion, ideal for field use.
Stable Performance: Each unit is factory-calibrated and tested to deliver consistent readings.
Environmentally Responsible: Low-power consumption extends battery life and reduces waste.
When held in hand, the detector feels lightweight yet solid, with a soft-touch matte surface that resists slipping even when gloves are worn.
The LCD screen offers crisp readouts, while the LED ring glows bright green for safe and red for live voltage detection.
The click-tactile power button and adjustable sensitivity wheel provide intuitive control.
An integrated flashlight casts a focused beam, helping professionals work confidently in dark panels or basements.
Its ergonomic clip-on design makes it easy to carry in a shirt pocket or tool belt throughout the day.
Professional OEM Support: We offer branding, custom packaging, and bulk solutions for global distributors.
Quality Assurance: Every voltage detector undergoes a 100% functional test before shipment.
Competitive Pricing: Factory-direct manufacturing ensures cost efficiency without compromising performance.
Fast Delivery & Global Shipping: Standard orders processed within 5–7 working days.
Dedicated After-Sales Service: Technical guidance and replacement support for long-term partnerships.
Our goal is not only to sell a tool but to deliver a reliable safety companion for every professional electrician.
