This pen-shaped brake fluid tester can easily help determine whether it's time for you to change your brake fluid.
Developed for professional use in automotive repair shops and servicing. 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. The high moisture content will lead to a lower boiling point, affect braking performance.
Accurate and Science OrientedBrake fluid detection pen is based on the change in conductivity to determine the moisture change of brake fluid.
Multiple UtilizationTesting DOT 3, DOT 4, DOT 5 brake fluid, only takes seconds to know the results.
Clear Indication5 LEDs to indicate percentage of water in the brake fluid.
