Features: This is an advanced voltages tester designed to accurately measure alternating current voltages values, suitable for household and industrial electrical systems. Equipped with none-contact sensing technology, it safely identifies live wires without physical contact, ideal for pre-checking voltages presences before operate. The tester can distinguish between live (hot) and neutral wires, providing critical guidance for safe electrical construction and maintenance. Featuring a highly definition color screen, it ensures clear visualization of voltages readings, enhancing usability in various lighting conditions. Built with a 500mAh rechargeable battery, and supports long-term repeated use. Specifications: Component: ABS Size: about 170x34x30mm/6.69x1.34x1.18inch voltages ranges: 0.1V-300 Induction voltages ranges: 12V-1000V Package Includes: 1pc Digital voltages Tester Pen note: Please allow 1-2cm errors due to manual measurement, make sure that you do not mind before you order.
