HABOTEST HT95A-PH1 Digital Voltage Tester Screwdriver 6V-390V AC Non-Contact Voltage Detector Pen

1. Combines a high-hardness Lovan alloy steel screwdriver bit with a smart digital AC voltage tester. Built for ultimate durability and wear resistance, allowing you to quickly tighten or loosen screws on circuit breakers, outlets, and home appliances while performing electrical safety testing.
2. Powered by an upgraded responsive smart chip, this tester measures AC voltage from 6V up to 390V (50/60Hz). The high-definition LCD screen automatically lights up Green for normal status (--U) and Red with an audible buzzer alarm (HI) when high voltage is detected.
3. Insert the probe into sockets to instantly identify neutral lines and live lines. Trace along insulated wires in NCV mode to locate broken wires—the signal disappears immediately once passing the circuit breakpoint.
4. Features a protective insulated sleeve over the shaft to prevent short-circuit accidents in crowded electrical boxes. Even when batteries are completely depleted, touching a live conductor will still trigger an emergency high-voltage warning icon on screen.
5. Crafted with non-slip PP+TPE soft rubber secondary injection molding, weighing only 70g for effortless pocket carry. Automatically powers down after 5 minutes of inactivity to conserve battery life, with a 10-second anti-accidental touch protection feature.

Parameters:
1. Shell Material: PP + TPE dual-color injection overmolding
2. Bit Material: High-hardness alloy steel
3. AC Voltage Detection: Detection range: 6V - 390V, 50/60Hz
4. Measurement Accuracy: 6V - 390V: +/-(5%+5)
5. NCV Non-Contact Sensing: Safely senses AC voltage through air without touching wires or live exposed conductors
6. Live / Neutral Wire Identification: Socket measurement: Neutral wire displays --U (green backlight); Live wire displays HI (red backlight + buzzer alarm)
