The Labgear voltage detector pen offers a quick and simple method for non-contact detection of AC voltages ranging from 90v to 600v, with enhanced sensitivity for accurate readings. This ergonomic, pen-style voltage finder provides dual feedback through a glowing red LED at the tip and a clear audible tone upon voltage detection, ensuring safety and reliability. It is versatile for identifying AC voltage in socket outlets, switches, circuit breakers, fuses, and luminaries. The tester can also detect breaks in conductors by tracing along cables and identify blown fuses within a circuit. For added convenience, it features a built-in LED torch to illuminate dark or hard-to-reach workspaces, allowing for better visibility during use. Founded in 1932, Labgear is a British company known for its high-quality products, innovation, reliability, and excellent customer service.
