Proster NCV Tester Pen + Circuit Breaker Finder

⚡【Non-Contact Safety & Audible/Visual Alarms】 Ensure maximum safety with non-contact voltage detection. Simply place the tip near outlets, wires, or circuit breakers. When voltage is detected, the LED indicator lights up red and a buzzer emits audible beeps. The alarm frequency increases as the voltage level rises or the probe gets closer, giving you clear, intuitive feedback without touching live wires 💡【Built-in LED Flashlight for Dark Areas】 Never work in the dark again. The probe features a bright built-in LED flashlight that illuminates dark breaker panels, cramped crawlspaces, and dimly lit outlets. This ensures you can work safely and efficiently regardless of lighting conditions 🏠【Live/Neutral Wire Identification & Breakpoint Finder】 Easily distinguish between live and neutral wires with the intuitive alarm system. When the sensor approaches a live wire, the alarm activates strongly; when near a neutral wire, the signal remains silent. This function also works as a wire breakpoint locator, making it an essential tool for electricians and DIYers troubleshooting circuits 🔋 Rechargeable Electrical Circuit Tracer Set. Never Buy Batteries Again & See Everything on the Color Screen! Our rechargeable lithium-ion power means it's always ready. Plus, the transmitter’s large, backlit color LCD gives you a crystal-clear readout—no more decoding blinking lights. See wiring status, GFCI trip time (in ms), and more at a glance 🎯 Pinpoint Breakers in 3 Steps, No Guesswork Stop flipping breakers blindly. Just: 1) Plug the smart transmitter into any outlet, 2) Scan the panel with the receiver, and 3) Follow the clear rising beep and LED bar to the exact breaker. Advanced signal processing cuts through interference for bulletproof accuracy on 90-135V AC systems 🛡️ Your All-in-One Electrical Safety Inspector This is 4 tools in 1: a precision circuit tracer, a 6-condition GFCI/outlet tester, a non-contact voltage (NCV) detector for quick safety checks, and
