High sensitivity non-contact voltage tester with a 24 V to 1000 V AC range. It provides accurate readings without contact, helping you stay safe while locating live lines. NCV detection with buzzer and a synchronous light for quick, easy identification of live wires. No contact needed. Auto shut-off and a low-voltage indicator conserve power and extend battery life, reducing maintenance in the field. Red and green indicator lights clearly show the presence and status of voltage, supporting safe decision making during use. Use scenarios: - Residential and office wiring: check outlets, switches, and circuits before work to verify power status. - Electrical panel and wiring verification: identify live lines in panels or equipment during installation or maintenance. - Construction and renovation sites: scan cables and conduits before drilling or wiring to ensure safety.
