Description

The Proster Voltage Tester Pen makes electrical work safer and faster for both professionals and DIY enthusiasts. Its non-contact design lets you identify live and neutral wires without touching the conductor, reducing the risk of shock. With dual voltage ranges-48V-1000V for low sensitivity and 12V-1000V for high sensitivity-you can easily switch modes by pressing the "S" button to match the task at hand. The built-in audible buzzer and red LED flash provide clear visual and sound alerts, so you never miss a live wire even in noisy environments. A handy flashlight function adds extra visibility in dark closets, basements, or under-cabinets, turning the pen into a versatile tool for any job site. Its compact, pen-shaped body fits comfortably in your hand and pocket, making it ideal for quick inspections, outlet checks, and breaker panel testing. Trust Proster to deliver reliable performance, simple operation, and the confidence you need when working with AC voltage.
