Brake fluid tester is a testing tool specially used to detect the moisture content of automobile brake fluid DOT3/ DOT4/ DOT5.1. It determines the moisture change of brake oil according to the change of conductivity. The water content of 1%-2% is qualified, and 3%-4% enters the early warning state. If the water content of the brake fluid ≥ 4%, it will cause the boiling point to decrease, affect the brake performance, and corrode the wheel cylinder to endanger driving safety. So when the brake fluid tester display ≥ 4%, the brake fluid must be replaced immediately. Brake fluid tester pen has a short sensor probe on the tip. The moisture content detection result will clearly show through the color LED lights on the pen body. There is a connection universal hose between the handheld brake fluid tester and the sensor probe, which is convenient for collecting data in various occasions. The LCD display with backlight function shows the test results in the form of an analog bar chart. It makes water test result to be more intuitive.
