Car Brake Fluid/Brake Oil Moisture Test Pen

Brake Fluid Tester Description:

The brake fluid test pen is used to test the quality of brake fluid. The test result of the percentage of water content in the brake fluid is displayed by the number of 5 LED lights on the test pen. The brake fluid test pen determines the change of water content in the brake fluid based on the change of conductivity, and clearly displays the degree of water content through the light-emitting diode. High water content will lead to a lower boiling point and affect the braking performance. Red light indicates that the brake fluid needs to be replaced, green light indicates that it is in good condition, and yellow light indicates that it is in fair condition.

To Check Fluid Quality:

Press the button for power on, green LED will light up.
Insert the tester into reservoir for a second , then the results will be indicated correctly by LEDs.
Auto power off .

Indications:

Green: Battery OK, i.e.: No Water Contained in the Brake Fluid
Yellow: Less than 1% of Water Content in Brake Fluid
Yellow/Yellow: Approximately 2% of Water Content in Brake Fluid
Yellow/Yellow/Red: Approximately 3% of Water Content in Brake Fluid;
The Brake Fluid Should be Changed
Yellow/Yellow/Red/Red: at least 4% of Water Content in Brake Fluid;
The Brake Fluid Must be Changed Urgently, Extreme Danger.

Note

1. If the green LED does not light up after pressing the power button for a long time, the battery needs to be replaced;
2. Please clean the test probe with clean water after each use of the test pen;
3. Please do not expose the brake fluid to the air for a long time, because the brake fluid has strong water absorption.

Preparation before testing
Unscrew the cap of the brake fluid reservoir and remove the cap of the test pen. Immerse the test probe into the brake fluid in the reservoir.

Water content test
Press the power button and the green LED will light up. Keep it for 1 second, the test result will be displayed by the lighting of the LED light, and after the test is completed, the test pen will automatically turn off after 12 seconds.
