Feature

●Detection Principle: The brake oil test pen measures the moisture change of the brake oil based on the change in conductivity, and clearly displays the degree of moisture content through the light-emitting diode. High moisture content will cause the boiling point to decrease and affect the braking performance.
●Indication Effect: The test result of the brake fluid water content percentage is displayed by the number of the 5 LED lights on the test pen. Red light indicates that the brake fluid needs to be replaced, green light indicates that the condition is good, and yellow light indicates that the condition is acceptable.
●Portable: This test pen is small, lightweight and easy to carry. Users can perform brake fluid testing anytime and anywhere without going to a professional repair shop or service station.
●Packaging Details: You will receive a black car brake fluid test pen with LED indicator light. This product can quickly detect the health status of car brake fluid, provide you with more accurate detection results, and remind you to replace the brake fluid when necessary to ensure your driving safety.
●Perfect After-sales: We are committed to providing you with a perfect shopping experience, if you have any usage problems, please feel free to contact us directly, we will solve the problem for you within 24 hours on working days.
