About This

Non-Contact Voltage Detection: Safely test AC voltage (12-1000V High Sensitivity / 48-1000V Low Sensitivity) without touching wires. Audible beeps and flashing LED lights instantly alert to live current in outlets, switches, or cables.
Safety Certified: Complies with CAT III 1000V/CAT IV 600V standards. Features low-battery alerts and insulated ABS housing for secure operation in industrial/home environments.
Live/Neutral Wire Identification: Distinguish live wire (strong signal) from neutral wire (weak/no signal) by placing the probe near wires or socket holes. Assists in breakpoint testing and circuit checks.
Audio-Visual Dual Alarm: Triple-intensity LED indicators (1-3 lights) and variable-frequency buzzer clearly signal voltage strength. Brighter lights and faster beeps indicate higher voltage or closer proximity to the source.
Built-in LED Flashlight & Auto Power Off: Illuminate dark workspaces with the pen-top LED light. Conserves battery via automatic shutdown after 5 minutes of inactivity or no signal detection.
Pocket-Sized & Portable: Lightweight pen design with clip for easy carry. Powered by 2x AAA batteries (included).
