Description
The brake fluid tester pen measures the water content in brake fluid based on changes in electrical conductivity. It clearly indicates the water proportion via LED indicators. High water content can lower the boiling point of the brake fluid, impair braking performance, and cause corrosion or rust buildup in the master cylinder and slave cylinder, potentially leading to seizure. This product is suitable for both automotive 4S shops and individual vehicle owners, offering simple, accurate, and fast use!

Key Features
Premium Materials: Unlike traditional ABS, this product features a more robust nylon housing paired with nickel-plated metal probes. It offers excellent protection against oil, oxidation, and corrosion, effectively withstanding brake fluid degradation to extend service life.
Clear LED Indicators: Equipped with five LED indicators, it visually displays brake fluid quality through green, yellow, and red lights: green indicates good condition, yellow signals acceptable but nearing replacement time, and red warns of immediate replacement needed. Test results appear quickly and are easy to understand without professional interpretation.
High Performance: It accurately measures water content in brake fluid from 0% to 3%, helping detect issues such as reduced boiling point and compromised braking performance due to excessive water. It provides early warnings of potential safety risks, enabling timely measures and preventing accidents caused by brake failure—ensuring comprehensive driving safety.
Cordless & Portable Design: It features a wireless design, compact size, and lightweight construction for easy portability and storage.
Easy to Use: With a simple design that doesn't require specialized mechanical knowledge, you can immerse the test probe directly into the brake fluid reservoir and get results within seconds. This allows individual car owners to perform brake fluid tests conveniently without visiting a repair shop.
Details
Safety-Enhanced Edges: This design prevents accidental scratches during regular use, ensuring your safety.
Premium Housing: The housing features a matte black design with excellent grippy properties, providing a premium grip and ensuring long-term reliability.
Application
This product is used for monitoring brake fluid condition and is compatible with mainstream brake fluid types such as DOT3, DOT4, and DOT5. It is suitable for professional technicians in 4S shops, specialized repair workshops, and individual repair stores, as well as for personal vehicle owners.
