Tester Specification: 1. To check the quality of brake fluid quality 2. 5 LEDs to indicate percentage of water in the brake fluid 3. Automatically power off 4. Operated by a LR03 AAA 1.5V battery ( Not included ) Tester Instructions: 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. Red indicates the brake fluid needs immediate replacement, green represents good condition, yellow indicates the state is acceptable but soon replaced. 1. the green LED lights = water content in the brake fluid H2O 2. the yellow LED lights = brake fluid water content H2O = 1.5% to 3%, can continue to use, test again six months later 3. the red LED lights = water content in the brake fluid H2O> 3%, can not continue to use the brake fluid needs to be replaced Red LED: change brake fluid 4.LED red flashing: battery replacement 5.LED yellow: low moisture content, check again in six months 6.LED green: brake fluid lines / cell row Tester Features: Five LED indicators show the test results more accurate. Testing DOT 3, DOT4, DOT5 brake fluid Press the switch to turn on the power, the green LED light that represents the battery properly, the green light does not shine on behalf To replace the battery Automatic shutdown Attention :1. Replace battery if the gree LED not light p 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! Packaging: 1* brake fluid tester
