【High-Quality Materials】: The shell of this low-voltage tester is made of ABS plastic insulation material, which has excellent flame retardancy and hardness. The high-quality metal probe and imported chip design make it more wear-resistant, durable, safe, and have a longer service life than ordinary power probes on the market. You can use it with confidence! 【3-70V Wide Test Range】: The test light can measure a voltage range of 3-70V, which can be used for DC 6/12/24/48/60/70V systems. The sharp and pointed stainless steel probe can accurately penetrate wires and measure hard-to-reach areas. In addition, the circuit tester is equipped with a thickened clip for easy one-handed operation. 【LED Accurate Digital Display】: The surface of the electrical tester is equipped with an LED digital display. After the tester is properly connected and electrically used, it can accurately display the device's voltage (accuracy: ±1-3). Whether it's day or night, the digital display is clearly visible. This circuit tester also supports positive and negative pole analysis: red represents the positive pole and green represents the negative pole. 【Extended Coiled Cable】: The fuse tester is designed with a flexible PU coiled spring cable, and its 110-inch thickened and extended coiled cable allows you to use the automotive test light more flexibly and conveniently. There is also a soft metal spring protector at the connection between the cable and the continuity tester to prevent the cable from breaking due to long-term use. 【Multifunctional Use】: The voltage test pen can be used for circuit detection of various models such as cars, trucks, SUVs, forklifts, RVs, tricycles, electric vehicles, motorcycles, off-road vehicles, etc., such as testing fuses, battery voltage, line continuity, ACC, engines, lights, turn signals, faulty sockets, etc. Of course, you can also use it to test other 3-70V DC lines and circuits.
