Make every electrical check faster, safer, and easier with the MUFASHA Non-Contact Voltage Tester Pen. This compact AC voltage detector lets you confirm the presence of live voltage without ever touching a bare wire, so you can work with confidence whether you are a professional electrician or a weekend DIYer.
Built around reliable magnetic induction sensing, the tester picks up the induced voltage field around AC wiring and alerts you instantly with a clear signal. The closer you get to a live conductor, the stronger the alert becomes, giving you an intuitive sense of exactly where the voltage is hiding.
With a wide 12-1000V AC detection range, it handles everything from low-voltage circuits to standard household and industrial lines, making it a genuinely versatile tool for troubleshooting, installation, and maintenance work.
Use the tester to check whether an outlet, switch, or cable is live before you begin work, to confirm live, neutral, and ground wires, and to trace breaks in AC power lines. It is ideal for electricians, maintenance technicians, and home DIY enthusiasts handling wiring, repairs, and installations.
Simply install two 1.5V AAA batteries, press and hold the power button for more than 2 seconds to switch it on, and bring the tip near the conductor. The alert frequency rises as you get closer to a live wire and fades as you move away.
