Brake oil test pen is based on changes in conductivity to determine the brake oil moisture changes. It clearly shows the degree of moisture content through the light-emitting diodes, high water content will lead to lower boiling point, affecting the braking performance, but also corrosion of the total cylinder and cylinder lead to rust and so on. Red light that the brake oil needs to be replaced immediately, green light that the state is good, yellow that state is acceptable, but about to be replaced. This product can be used for car 4S shop and owner, the product is simple and accurate!

The meaning of the indicator light:
Green: battery OK, that is, brake oil does not contain water
Green / yellow: brake oil in the water below 1%, the brake oil performance is good, can be assured use
Green / yellow / yellow: brake oil in the water about 2%, brake oil can continue to use
Green / yellow / yellow / red: water content of about 3% brake oil, it is recommended to replace the brake oil
Green / yellow / yellow / red / red: brake oil in water at least 4%, need to immediately replace the brake oil
