Digital Brake Fluid Tester

This new and much improved brake fluid tester will accurately display water moisture content in the brake fluid. The unit comes with a backlit screen and inbuilt flashlight for when in dimly lit areas.
Includes a buzzer alarm function and auto shut off after 5 minutes. 
1% or less is a good condition, no need to replace the fluid.
1% - 2.5% means the performance is reduced but still usable.
3% or above indicates a serious decrease of performance and needs replacing.

Suits Fluids: DOT3, DOT4, DOT5.1
