Non-Contact Digital Voltage Tester 12–300V AC Voltage Detection Non-Contact NCV Sensing Live/Neutral Wire Identification Positive/Negative Polarity Detection Continuity Testing Flashlight Illumination USB Charging Capability Circuit Inspection and Repair Tool

Five-Point Description:

Multifunctional Digital Voltage Tester: Supports AC voltage measurement (12–300V, 50/60Hz) with a three-digit dual-colour display. Normal readings appear green, while high voltage triggers red alerts for clear, intuitive feedback. Suitable for testing household wiring, sockets, switches and other electrical components.

Non-contact NCV Sensing: Rapidly detects AC voltage signals. Weak voltage triggers intermittent buzzer sounds with ‘--L’ display; strong voltage produces continuous buzzer sounds with red ‘--H’ display, aiding voltage strength assessment and enhancing testing safety.

Positive/Negative Polarity Detection & Continuity Testing:
Press and hold the ‘Continuity Test’ button. Touch the probe to the battery's positive terminal while touching the negative terminal with your hand. The screen displays ‘--P’ with a beep, quickly identifying the positive battery terminal. Also supports circuit continuity testing, facilitating routine troubleshooting for electricians.

Flashlight Illumination & Data Hold:
Built-in illumination. Press and hold the ‘①’ button to activate/deactivate the flashlight, ideal for low-light conditions. Data hold function facilitates recording measurement results.

USB Charging & Eco-Friendly Design: Incorporates a 3.7V/220mAh lithium battery, rechargeable via USB port, eliminating frequent battery replacement. Low-battery alert (below 3.3V) and 15-minute auto-shutdown extend operational duration. Compact and portable (approx. 46g), ideal for electricians and maintenance personnel to carry.
