Brake Fluid Tester Pen

Do you want to know if it's time to change your brake fluid? This is your remedy; it also stops you from exposing the brake fluid to the atmosphere for an extended period of time because it is hygroscopic. 

ABOUT

Tester      Instructions: Brake fluid detection pen is based on the change in conductivity to determine the moisture change in brake fluid. It shows clearly the extent of moisture contained by the light-emitting diode; high moisture content will lead to a lower boiling point and 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<1.5%, brake fluid qualified

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
