Circuit tester

This digital circuit tester is designed for checking electrical circuits in vehicles and other compatible low-voltage systems during routine inspection and maintenance. With a test range of 3-30V, it is suitable for common automotive circuit testing applications, including checking circuit voltage and identifying positive or negative polarity. The cellulose acetate fiber construction provides a practical material configuration for everyday workshop use, while the 304 stainless steel probe is designed for contact with the circuit under test. An LED digital display provides a clear way to observe test results during operation, and the LED indication uses green (-) for negative polarity and red (+) for positive polarity. This straightforward design makes the tester suitable for automotive repair shops, garages, service technicians, and automotive accessory distributors. For B2B applications, the product can be positioned as a 3-30V digital automotive circuit tester for vehicle electrical inspection, circuit checking, and routine maintenance.
