## Features

- LED Digital Display: This detection pen is designed with an LED digital voltage display, which allows you to clearly see the detection value. In the bidirectional current and voltage test mode, you can ground the alligator clip, clamp the negative pole with the clip, test the positive pole with the tip of the pen, and turn on the green light. Hold the positive pole with the clip, and measure the negative pole with the tip of the pen, and a red light will appear.
- Excellent Material Selection: This circuit detection pen adopts ABS high-hardness shell, durable, good insulation performance. The thickened test wire is used, which has good flexibility and can be bent. The wire mouth is protected by a spring, which will not cause danger due to the disconnection of the wire skin over time.
- Product Details: You will receive 1 x digital display test pen with a measuring range of 3V-70V, a pen body length of 4 inches, a probe length of 3 inches, and test leads are 3.9 feet long, which is sufficient for your use. The long probe ensures you can reach tight places with more accuracy and sensitivity.
- Ensure Safe Driving: The automobile circuit test pen is mainly used to detect parameters such as voltage, current, and resistance in automobile circuits. This device can help detect and eliminate faults in the automobile circuit system, ensure you can safely conduct circuit testing, and improve the reliability and safety of the car as a whole.
- Wide Application: This test pen can be used for automobile fuse testing, generator testing, power frequency voltage testing, circuit positive and negative polarity identification, etc. Suitable for circuit testing of most automobiles. In the maintenance of automobile circuit systems, efficient troubleshooting and safe problem solving can be achieved.
