【High-Quality Materials】: The casing of this low-voltage tester is made from ABS plastic, offering excellent flame resistance and durability. The high-quality metal probe and imported chip design make it more wear-resistant, long-lasting, safe, and have a longer lifespan than typical voltage detectors on the market. You can use it with confidence! 【3-70V Wide Measurement Range】: This test lamp can measure a voltage range of 3-70V, suitable for DC 6/12/24/48/60/70V systems. The sharp and sturdy stainless steel probe can precisely pierce through wires and measure hard-to-reach areas. Additionally, the circuit tester is equipped with a thicker clamp for one-handed use. 【LED-Backlit Digital Display】: The surface of the electrical tester is equipped with an LED digital display. When the tester is correctly connected and used electrically, it can accurately display the unit's voltage (accuracy: ±1-3). Whether it's day or night, the digital display is clearly visible. This circuit tester also supports analysis of positive and negative poles: red represents the positive pole, and green represents the negative pole. 【Extended Spring Wire】: The safety tester is designed with a flexible PU spiral spring wire, and its 110-inch thickened and extended spring wire allows you to use the car test lamp more flexibly and comfortably. There is also a soft metal spring guard at the connection between the wire and the continuity tester to prevent the wire from breaking during long-term use. 【Multi-Functional Use】: The voltage test pen can be used for circuit detection of various models such as cars, trucks, SUVs, forklifts, campers, three-wheelers, electric cars, motorcycles, off-road vehicles, etc., for example, testing fuses, battery voltage, line continuity, ACC, engines, lights, turn signals, faulty sockets, etc. Naturally, you can also use it to test other 3-70V DC wires and circuits.
