The Qboonpt Car Brake Fluid Test Pen is a Hydraulic Oil Moisture Analyzer Troubleshooter that features 5 LED indicators, making it a reliable Diagnostic Testing Tool for DOT3, DOT4, and DOT5.1 brake fluids. [High Quality Performance] The brake fluid detector utilizes a nickel-plated metal probe to accurately detect changes in brake fluid level, oil, and oxidation, ensuring resistance to corrosion. The matte black plastic case provides better skid resistance and a pleasant body texture.

[Instructions] The indicator light display functions as follows: Green light indicates the power supply is in good condition and there is no water present. Green/yellow light signifies the water content is less than 1%. Green/yellow/yellow light means the water content is close to 2%. Green/yellow/yellow/red light indicates the water content is close to 3%, and it is recommended to replace the brake fluid. The indicator light displaying green/yellow/yellow/red/red signifies the water content is higher than 4%, and the brake fluid must be replaced immediately.

[Scope of Application] This brake fluid tester is suitable for testing the moisture content in DOT-3, DOT-4, and DOT-5.1 brake fluids.

[Easy to Carry] The design features no cable connectors, making it compact, lightweight, and easy to carry and use. The brake fluid detector requires a single AAA 1.5V battery, which is not included in the package.

[Attention] If the green LED light does not illuminate after pressing the power button for an extended period, the power supply needs to be replaced. After each use, please clean the test probe with clean water. It is important to avoid exposing brake fluid to air for a prolonged time, as brake fluid has a strong tendency to absorb water.

In summary, the Qboonpt Car Brake Fluid Test Pen is a versatile and reliable tool for diagnosing and maintaining the health of brake fluids in vehicles. Its high-quality construction, user-friendly features, and comprehensive testing capabilities make it an essential addition to any automotive enthusiast's toolkit.
