ANENG B21 NCV Voltage Tester Pen, Rechargeable AC 30~1000V Non Contact Detector, Live/Null Wire Breakpoint Finder Screwdriver, Electrician Test Tool
DESCRIPTION
Non-Contact Voltage Detection (NCV): Detect AC voltage from approximately 30V to 1000V without directly touching the conductor. Simply bring the sensing tip close to a wire, outlet, switch, or electrical component. The tester provides visual and audible alerts when voltage is detected.
Contact Voltage Testing: The B21 also supports direct AC voltage measurement in the approximately 3–600V range, providing additional functionality when contact testing is appropriate and performed according to the manufacturer's instructions.
Live & Neutral Wire Identification: The tester can help distinguish between live and neutral conductors by detecting differences in the electrical field and displaying the result through its screen, backlight, and audible alarm.
Wire Breakpoint Detection: Useful for troubleshooting electrical wiring, the breakpoint function can help locate where an energized wire or circuit stops carrying detectable voltage, making it easier to identify potential interruptions.
Continuity / On-Off Detection: The B21 can perform continuity checks with an audible indication, helping identify whether a circuit or wire has an electrical connection.
Dual-Color Digital Display: The backlit display provides easy-to-read testing information. Different display colors help indicate electrical conditions and voltage levels, making readings easier to interpret in work areas with limited lighting.
Built-In LED Flashlight: A white LED light is integrated into the tester, allowing it to illuminate outlets, electrical panels, wiring, and other dark work areas.
USB Type-C Rechargeable Battery: The tester uses a rechargeable 14500 lithium battery and can be recharged through its Type-C charging connection, eliminating the need to regularly replace disposable batteries.
2-in-1 Tester & Screwdriver Design: The B21 combines electrical testing with interchangeable screwdriver bits. The replaceable magnetic bits make the tool useful for basic fastening and electrical maintenance tasks without carrying a separate screwdriver.
Insulated Handle & Safety Design: The tester features an insulated rubber/TPE-style handle and is designed with electrical safety in mind. Product documentation lists CE CAT II 1000V / CAT IV 600V protection ratings; always follow the manufacturer's instructions and applicable electrical-safety practices.
