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
Exceptional Build Quality: Moving beyond conventional ABS, this product is made from a reinforced nylon shell complemented by nickel-plated metal detection probes. It delivers superior defense against oil, oxidation, and corrosion, effectively withstanding breakdown from brake fluid to prolong its functional lifespan.
Intuitive Visual Feedback: With a set of five LED indicators, it offers clear color assessment of brake fluid status: green for optimal condition, yellow for acceptable yet approaching replacement, and red for urgent replacement required. Results are displayed rapidly and are straightforward to interpret without technical expertise.
Excellent Performance: The tool precisely detects water proportion in brake fluid from 0% to 3%, identifying risks like lowered boiling point and diminished braking efficiency caused by excessive water. By providing early alerts to potential hazards, it supports proactive maintenance—helping prevent brake-related failures and enhancing overall driving safety.
Cordless & Compact Portability: Designed without cables, it is small, lightweight, and highly portable for convenient storage and on-the-go use.
Simplified Operational Design: Its user-friendly design doesn't require professional skills—simply place the probe into the brake fluid reservoir and get the results in seconds. This empowers everyday car owners to easily check their brake fluid anytime, eliminating the need for a repair shop visit.
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.
