【Scope of Application】This brake fluid tester is compatible with mainstream hydraulic brake fluid models of DOT 3, DOT 4, and DOT 5.1, covering most vehicle types including passenger cars, SUVs, trucks, and motorcycles. No need to purchase separately for each vehicle model, meeting the diverse testing needs of individual car owners, repair shops, and car enthusiasts, eliminating the hassle of "buying the wrong fluid that won't work."
【5 LED Indicator Lights】Built-in high-precision sensors provide real-time feedback on brake fluid moisture content via 5 different colored LEDs: green (safe), yellow (warning), and red (danger). Even without professional knowledge, you can quickly determine the condition—a green light indicates good brake fluid condition, while a red light indicates timely replacement, preventing safety hazards such as brake failure and increased braking distance caused by water absorption in the brake fluid.
【Quick Testing】No complicated tools are required
testing can be completed in just 3 steps: ① Open the pen cap
② Insert the test probe into the brake fluid reservoir
③ Wait 3 seconds and check the LED indicator status. Even seniors and beginners can easily use it, eliminating the need to queue at repair shops and allowing for regular self-checks at home, saving time and testing costs.
【Durable Material】This brake fluid tester probe is made of corrosion-resistant metal, which is anti-oxidant and anti-aging, and will not easily rust or be damaged after contact with brake fluid. The pen body is made of high-strength ABS plastic, which is non-slip, wear-resistant, and drop-resistant. It has a built-in low-power chip, allowing for hundreds of uses on a single button battery, providing long-lasting power and eliminating the need for frequent battery replacements.
【Convenient Design】Excessive moisture in brake fluid is one of the core causes of brake system failure. This brake fluid tester helps you anticipate safety risks, protecting you during daily commutes, long-distance driving, and mountain driving. The product is only 15cm x 3cm and weighs approximately 50g, making it small and lightweight enough to fit in a pocket.
