This brake liquid tester is used to determine the moisture according to conductivity change and check the car brake oil quality.
Unscrew the brake fluid reservoir and pull off the cap of the brake fluid tester then dip the test probes into the brake fluid until up to the plastic rim of the device.
5 LED lights display the percentage of moisture content in brake fluid, provides more accurate test result, oil-proof and oxidation-proof, with good condition and high precision.
Designed without cable connector, portable and light weight, convenient to carry and use.
Directions for 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
