Features: Smart display: This voltage detector pen has an LCD screen, and the test results can be displayed on the large screen. Liquid Crystals Display: Our voltage detector pens feature state-of-the-art liquid crystals display technology that greatly enhances the reading experience even in bright sunlight or low light conditions. With light design: it can easily allow you to measure voltage and current in a dark environment. Multifunctional pen: The design of the universal pen of the voltage detector not only greatly expands the test function, but also has a small size and does not take up space. Fire line detection: By comparing the strength of the detection voltage, it is safe and easy to distinguish the fire line, and the wire that detects the strong voltage signal is the fire line.
