Feature:

The brake fluid tester is suitable for determining the quality of brake fluid.
The brake fluid tester determines the change in the humidity of the brake fluid based on the change in conductivity. The humidity is clearly displayed through the light-emitting diodes. The high content of water will lower the boiling point and then affect the braking performance. Red indicates that the brake fluid needs to be replaced immediately, green indicates that the brake fluid is in good condition, and yellow indicates that the brake fluid remains in good condition but will change.
Design without cable connector, fast and convenient
Power supply: 1.5V "AAA" x 1

Instructions:

5 LEDs indicate the percentage of water in the brake fluid:
0% LED: There is moisture content in the brake fluid
1% LED: water content, H2O≤1%, brake fluid is higher than the standard
2% LED: water content, H2O≤2%, still usable
3% LED: water content, H2O≤3%, the brake fluid is recommended to be replaced
4% LED: water content, H2O≥4%, brake fluid must be replaced

Packing list:

1 x brake fluid tester (without battery)

Notice:

1: After each test, you need to clean the test probe with a dry cloth or paper.
