High-Precision Brake Fluid Tester Pen for DOT3, DOT4, DOT5.1

The high-precision brake fluid tester pen is designed to ensure vehicle safety by allowing regular checks of brake fluid condition. When brake fluid absorbs water, it can lose efficiency and affect braking performance, which may pose safety risks. This device helps maintain the stability of the brake system, enabling timely replacement of degraded fluid to minimise hazards. Equipped with a high-precision probe, the tester quickly detects water levels in brake fluid and utilises a five-level LED indicator for clarity. The different LED colours correspond to varying percentages of water, facilitating easy interpretation of test results. Constructed with high-quality brass-plated metal probes for excellent conductivity and durability, this brake fluid tester features a sturdy plastic casing that is both corrosion-resistant and wear-resistant, ensuring longevity across various conditions. Operation is straightforward: simply press the power button to activate the device and insert the probe into the brake fluid. The LED indicators will illuminate based on detected water levels, and the tester automatically shuts off after 12 seconds to save battery life. Broadly applicable, this tester is compatible with DOT3, DOT4, and DOT5.1 brake fluids, making it suitable for most cars, motorcycles, trucks, and more. It serves both personal vehicle maintenance and professional repair needs without any hassle.
