BRAKE FLUID (BRAKE OIL) TESTER
OTB620
Product manual
Automobile brake fluid (hereinafter referred to as the brake oil) is used in the hydraulic brake system transfer pressure to
stop the wheel rotating liquid, its quality is good or bad, choosing and using correctly or not, is directly related to driving
safety. With the rapid development of the automobile industry, the trend of automobile speed is becoming more and more
obvious, and the application of brake oil is higher. The brake oil is very important at home and abroad, and the brake oil is
considered as safe fuel for the car. The brake oil tester
OTB620
can quickly and accurately test the brake oil quality, check
the water content, indicate your brake oil state, and provide the reliable basis for your maintenance and replacement.
Different types of brake oil are different according to its moisture content, the boiling point will be different, and replace
the brake oil with excessive water content in time to ensure your safe driving.
Product features:
1.
Quickly detect brake oil performance, test the water content of brake fluid, quickly detect the brake fluid, and facilitate the replacement of
brake fluid in time. It is applicable to the test of the brake fluid of DOT3, DOT4 and DOT5.1. The LCD screen displays the test results,
which is intuitive, accurate and portable.
2.
Backlight function makes it easy to read data in a dark environment.
3.
With alarm function, when the brake oil test needs to be replaced, there is a sound alarm.

The brake oil detector is based on the change of conductivity to measure the water change of brake oil. It clearly shows the degree of
moisture content through the LCD screen, and the high moisture content can cause the boiling point to decrease and affect the braking
performance. When the LCD screen shows a value of less than 0.1 percent, it indicates that the purity is extremely high, less than 1%
indicates that the state is in good condition, and less than 2.5% indicates that the state is still good, and that the brake oil needs to be
replaced by more than 3%~ 4%.
