Universal Brake Fluid Tester with LED Indicators

Quick and Accurate Brake Fluid Testing

If your car brake fluid is too watery, it can significantly reduce its boiling point, decrease braking force, extend braking distance, and impair overall brake performance. Our brake fluid tester is designed to quickly check the water content and alert you to the need for a timely change. It is suitable for testing DOT3, DOT4, and DOT5.1 brake fluids.

Five Colorful LED Indicators

This tester features five LEDs with three distinct colors to indicate the percentage of water in the brake fluid: - Green: Good condition, no immediate action needed. - Yellow: Acceptable condition, but a change is recommended soon. - Red: Immediate replacement required.

Easy and Intuitive Operation

Using our tester is straightforward and quick. Simply insert the metal probe into the brake fluid, wait a few seconds, and the corresponding LED will light up to display the result. Once the test is complete, the tester automatically turns off after 12 seconds.

Durable and Reliable Construction

Crafted from brass-plated metal for excellent electrical conductivity, this tester is water-resistant, oil-resistant, and corrosion-proof, ensuring durability over prolonged use. The black matte plastic case provides a comfortable, non-slip grip, enhancing usability during tests.

What You Get

You will receive a high-quality brake fluid tester. It is compatible with AAA batteries (not included), so please ensure you have them on hand. After each test, clean the metal probe with water and remove the battery to conserve power.
