Brake Fluid Testing Tool for All Cars and for DOT3/4/5

Product Introduce: 1. The brake fluid tester is suitable for testing brake fluid quality. Brake Fluid Tester is according to the variation of electrical conductivity to determine the moisture content of the brake fluid change.It through the light-emitting diodes clearly shows the degree of moisture. High content moisture will reducing the boiling point, and then affect the braking performance. Red indicates brake fluid need to be replaced immediately, green indicates brake fluid in good condition, yellow indicates brake fluid stays good, but is going to change. 2. Designed without cable connector. 3. Fast and convenient. 4. Suitable for DOT3 / DOT4/DOT5 testing. Product function: automobile brake oil/brake fluid detection Applicable battery: 1 AAA battery (without battery) Color: Black Product bare weight: 40g Package size: 60*215*30mm Application: All automotive brake fluid/brake fluid, DOT3/4/5 brake fluid can be tested. Directions of Using: 5 LEDs indicating the water % in the brake fluid : 0% LED:there is on water content in brake fluid 1% LED: Water Content, H2O≤1%, brake fluid is above standard 2% LED: Water Content, H2O≤2%, still can use it 3% LED: Water Content Water Content, H2O≤3%, brake fluid should be changed 4% LED: Water Content Water Content, H2O≥4%, brake fluid must be changed Notes: 1. After every testing,you need clean the test head with dry cloth or paper.
