Product introduction:
The brake fluid detection pen is to measure the moisture change of brake fluid according to the change of electrical conductivity. It clearly shows the degree of moisture through the light-emitting diodes. High moisture content will reduce the boiling point and affect the braking performance. It will also corrode the brake master cylinder and the wheel cylinder, resulting in rust and stuck. Red light means the brake fluid needs to be replaced immediately, green light means it is in good condition, and yellow light means it is in good condition but is about to be replaced. This product can be used by car 4S shops and car owners, and the product operation is simple, accurate and fast
Detailed explanation of the meaning of the indicator light:
Green: The battery is OK, that is, there is no water in the brake fluid
Green/Yellow: The water content of the brake fluid is less than 1%, the brake fluid has good performance and can be used with confidence
Green/Yellow/Yellow: The water content in the brake fluid is about 2%, and the brake fluid can continue to be used
Green/Yellow/Yellow/Red: The water content in the brake fluid is about 3%, it is recommended to replace the brake fluid
Green/Yellow/Yellow/Red/Red: The water content in the brake fluid is at least 4%, the brake fluid needs to be replaced immediately
Reminder: After each test, wipe the liquid part of the test point with a dry cloth or paper
