Practical Mini OBD2 Electronic Brake Fluid Test Pen General Car Diagnostic Tool

Specification1. Check the quality of car brake oil2.5 LED lights display the percentage of water in the brake fluid3. Automatic shutdown4.1 LR44 button battery (not included)Instructions: The brake fluid detection pen judges the change of brake fluid moisture based on the change of conductivity. It clearly shows the degree of moisture contained in the light-emitting diode, high moisture content will cause the boiling point to decrease and affect the braking performance. Red indicates that the brake fluid needs to be replaced immediately, green indicates that it is in good condition, and yellow indicates that the condition is acceptable but will be replaced soon.1. Green LED light = water content of brake fluid H2O<1.5%, brake fluid is qualified2. Yellow LED light = water content of brake fluid H2O=1.5%~3%, you can continue to use it, and test again after six months 3. The red LED light is on = the water content in the brake fluid H2O>3%, the brake fluid cannot be used continuously, and the red LED needs to be replaced: replace the brake fluid4. LED red light flashes: replace the battery5. LED yellow: low water content, check again after six months6. LED green: brake oil line/battery row Features: five LED indicators show the test results more accurately. Check DOT 3, DOT4, DOT5 brake fluid, press the switch to turn on the power, the green LED light means the battery is normal, the green light is off, it means automatic shutdown after replacing the battery. Technical parameters: Green: the battery is normal, that is, the brake fluid does not contain water. Green/Yellow: Brake The water content in the oil is less than 1%, the brake fluid has better performance and is easy to use. Green/yellow/yellow: The water content in the brake fluid is about 2%, and the brake fluid can be used continuously. Green/yellow/yellow/red: The water content of 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 must be replaced immediately, which is very dangerous.
