This multifunctional tool features the function of NCV AC voltage detector, zero/live wire discrimination, break point detection and LED flashlight. With digital screen for easy recognition and compact size for easy operation, it can be applied in electrical testing for both household and industrial use conveniently. Features: Non-contact design, NCV induction makes it safer to use. One hand easy operation, very convenient to use. Compact, lightweight and portable to carry. 12-1000V AC voltage detection range, low/ high sensitivity adjustable; dual alarm of digital screen display and buzzer makes it easy to use; LED flashlight ensures safety work in dark environments. Zero/ live wire recognition: the tester's detection induction is strong when it's a live wire, and the induction is weak when it's a zero wire.
