Non-Contact Voltage Tester | AC Live Wire Detector with Sound & Light Alerts
A compact non-contact voltage tester designed for fast and safe detection of live AC voltage. Featuring sound and light alarms, adjustable sensitivity, and zero-contact operation, this tester is ideal for electricians, installers, and home electrical safety checks.
This non-contact voltage tester provides a safe and efficient way to detect live electrical circuits without direct contact. Designed for everyday electrical inspection and troubleshooting, it identifies live and neutral wires using visual and audible alerts, helping reduce the risk of accidental electric shock.
The tester can detect live wires through insulation and thin walls (up to approximately 1 cm), making it ideal for concealed wiring checks during installations and renovations. A dual alarm system clearly differentiates voltage levels using colour-coded lights and sound alerts, while adjustable sensitivity allows users to tailor detection for different environments.
Additional features such as wire breakpoint detection and a built-in flashlight make this tester especially useful in low-light conditions and fault-finding tasks. Its lightweight, pocket-sized design ensures it is easy to carry and ready whenever needed.
Typical applications include:
-
Live wire and neutral wire identification
-
Electrical safety checks before work
-
Breakpoint detection in single-strand wires
-
Hidden wiring detection behind walls
-
Home, commercial, and maintenance inspections
