ANENG High-Precision Digital Smart Voltage Tester Pen With Non-Contact Induction

1. Voltage detection range: AC 450V (Max)
2. Indicator light logic: Red = High-voltage live wire; Green = Low-voltage/Neutral wire; Blue = Induced electric field detection
3. Core functions: NCV (non-contact voltage) sensing, live/neutral wire differentiation, and circuit continuity testing
4. Multifunctional induction voltage tester combining NCV non-contact voltage sensing, 450V contact AC voltage detection, live/neutral wire identification, and circuit continuity testing
5. Features a tri-color LED indicator and dual-alarm buzzer; includes a dual-purpose Phillips/flathead screwdriver bit and an insulated, non-slip handle
6. Weighs only 58g and is powered by a single AAA battery (not included); a portable, all-in-one tool ideal for home electrical maintenance, socket troubleshooting, and locating circuit breaks
7. Red, green, and blue lights correspond to different circuit states, accompanied by synchronized buzzer alerts; allows for quick identification of live wires, neutral wires, and induced electric fields in noisy construction sites or dimly lit distribution boxes
8. Non-contact NCV function detects live circuits through insulation without stripping wires; contact detection measures mains voltage up to 450V, catering to both concealed wiring checks and socket testing needs
9. One-button differentiation between live and neutral wires prevents incorrect wiring; supports continuity testing to quickly identify faults such as broken wires or blown fuses
10. Integrated dual-specification screwdriver tip (Phillips and flathead) allows for tightening terminal screws immediately after testing, eliminating the need to carry a separate screwdriver
11. Handle wrapped in insulating material for a secure, non-slip grip and effective protection against electrical hazards
12. Net weight: 58g
13. Dimensions: 19.2 x 3.3 cm
