Non-contact Voltage Detector

Non-contact voltage detection – safely identifies live wires without piercing insulation or touching bare conductors.

Adjustable sensitivity – allows fine-tuning for different circuit types, from crowded panels to isolated wires.

Audible alarm + flashing light – provides both sound and visual warnings so alerts are never missed in noisy or dark environments.

Built-in flashlight – illuminates dark junction boxes, breaker panels, and equipment cabinets for hands-free visibility.

Breakpoint detection & quick response – pinpoints exactly where a wire is broken or cut with instant feedback.

Automatic shut-down after ~5 minutes – preserves battery life when the tester is accidentally left on.

Low voltage alert – notifies user when battery power is low to prevent unreliable readings.

Model 10S (90V~1000V) – ideal for standard household and industrial AC voltage detection (110V/220V/480V systems).

Model 11S (24V~1000V with dual sensitivity) – adds 24V low-voltage mode for control circuits, security systems, doorbells, and HVAC controls, plus standard 90V~1000V mode.

Zero fire line distinction – helps electricians identify which wire is live (fire) versus neutral (zero) during troubleshooting.
