Automotive Brake Fluid Tester Digital LED Indicator

Product DescriptionSpecification:1. To check the quality of brake fluid quality2. 5 LEDs to indicate percentage of water in the brake fluid3. Automatically power off4. Operated by  AAA 1.5V battery (Not included)5. Color: Black
Tester Instructions:Brake fluid detection pen is based on the change in conductivity to determine the moisture change brake fluid.1. the green LED lights = water content in the brake fluid H2O less than 1.5%, brake fluid qualified2. the yellow LED lights = brake fluid water content H2O equal 1.5% to 3%, can continue to use, test again six months later3. the red LED lights = water content in the brake fluid Hydrogen molecule2 Oxygen molecule greater than 3%, can not continue to use the brake fluid needs to be replaced Red LED: change brake fluid4.LED red flashing: battery replacement5.LED yellow: low moisture content, check again in six months6.LED green: brake fluid lines / cell row
Packaging Included:1 * Brake Fluid Tester (Not included battery)
Attention :1.Replace battery if the gree LED not light up any longer after you press power on button.Wash the test probe with tab water after use.2.In case of skin contact with brake fluid,thoroughly wash the affected skin or clothing with water.3.Do not expose brake fluid to the atmosphere for a long time as the fluid is highly hygroscopic!



Brake fluid detection pen is based on the change in conductivity to determine the moisture change brake fluid. It shows clearly the extent of moisture contained by the light-emitting diode, high moisture content will lead to lower boiling point, affect braking performance.
