Enhanced Voltage Compatibility: Unlike standard testers that handle up to 48V, our advanced model supports a broad range from 3-60V DC. Ideal for diagnosing a variety of vehicle electrical issues, from automotive headlights and taillights to turn signal circuits and faulty sockets, ensuring comprehensive vehicle maintenance. Innovative Design with Nighttime Functionality: Equipped with an illumination feature, this electric test pen is perfect for low-light conditions. Additionally, it includes a needle guard to prevent accidental injuries, ensuring safety and convenience during use, even in the dark. Bidirectional Voltage Testing with LED Indicators: This versatile circuit tester allows connection to either negative or positive ground. It features a dual-color LED indicator, with red showing positive and green indicating negative polarity, simplifying the testing process and enhancing user safety. Clear and Precise Readings: The tester boasts a high-resolution LCD digital screen with blue backlight, offering clear visibility in both daylight and darkness. The display provides precise voltage readouts to 0.1V, making it easier to monitor and diagnose electrical issues accurately. and Safe Construction: Rated IP66 for water resistance, our tester is built to last with a stretchable 142-inch PU spring wire and a PA nylon anti-bending design at the wire end. The stainless steel probe is safely insulated, combining superior conductivity with enhanced safety features.
