Ensure electrical safety and diagnostic precision with the KAIWEETS Voltage Tester Pen, designed for both professionals and DIY users. This non-contact voltage detector offers dual sensitivity modes (AC 12V–1000V & 70V–1000V), making it ideal for everything from low-voltage wiring to household mains. With visual and audible signals, the tester alerts you to live or neutral wires with increasing intensity and a real-time percentage signal strength indicator. The LCD screen changes color—red for live/high voltage, green for null/low voltage—so you can instantly assess the risk. It also includes a bright LED flashlight, auto shut-off, and low battery alert, all housed in a compact, pen-style body.
