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. 1. How Dangerous of a bad quality Brake Fluid ? 1) The inferior brake fluid causes the brake failure easily,thereby lead to a accident2) The Brake fluid is related to the life of Brade pads, if doesn't take it seriously, the life of brake pads is worried. Good or Bad Distinguish accurately Our Brake Fluid tester designs 4 level digital led indicator that can provide the accurate water content for you. Functions:1.check the car brake oil quality2.5 LED lights display the percentage of moisture content in brake fluid,how the test results more accurate3.Press the button for power on, green LED will light up.4.Insert the tester into reservoir for a second , then the results will be indicated correctly by LEDs.5.Testing for DOT 3, DOT4, DOT5 brake fluid6.Auto power off, Supports 1 LR03 AAA batteries (Battery not included)Accurate To 1% For TEST The Metrics is accurate to 1%, it can help you to know the situation of Brake Fkuid more clearly Technical parameters:Green: Battery OK, that is, brake fluid does not contain waterGreen / yellow: brake oil in water content of less than 1%, better brake fluid performance, ease of use. Green / yellow / yellow: brake oil in water content of about 2%, brake fluid can continue to use.Green / yellow / yellow / red: brake oil in water content of about 3%, the proposed replacement of brake fluid.Green / yellow / yellow / red / red: brake oil in water content of at least 4%, the brake fluid must be replaced immediately responsible for very dangerous. How to use Brake fluid tester ?Step 1 : Open car's front coverStep 2 : Find the brake Oil tank mouthStep 3 :Dip test probes and read the Led lightsStep 4: Recover the car's front cover Package List:1 x a brake fluid tester (Battery not included) 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 FluidYellow: Less than 1% of Water Content in Brake FluidYellow/Yellow: Approximately 2% of Water Content in Brake FluidYellow/Yellow/Red: Approximately 3% of Water Content in Brake Fluid; The Brake Fluid Should be ChangedYellow/Yellow/Red/Red: at least 4% of Water Content in Brake Fluid; The Brake Fluid Must be Changed Urgently, Extreme Danger . Notice * Please replace battery if the Green LED does not light up after you press button power.* Wash the test probe with tap water after use.* If you skin or clothing contacted with fluid, please use the water to wash. * Do not expose brake fluid to the atmosphere for a long time as the fluid is highly hygroscopic!* The monitors differ from one to another, the picture is only for reference, please make the object as the standard.
