The Automotive Brake Fluid Tester Pen is a professional, portable diagnostic tool designed to quickly and accurately measure the moisture content in brake fluid. High moisture content reduces the boiling point of brake fluid, compromising braking performance and creating a serious safety hazard. This tester allows both professional mechanics and DIY car enthusiasts to instantly check the health of brake fluid, determine if replacement is needed, and ensure safe driving conditions.
With its compact size, simple operation, and high-precision measurement, this tester pen is an essential tool for regular vehicle maintenance, helping you avoid costly brake repairs and dangerous driving situations.
✓ High-Precision Measurement: High-quality, corrosion-resistant probe with high sensitivity delivers accurate moisture content readings with minimal measurement error.
✓ Compatible with All Common Brake Fluid Types: Works with DOT3, DOT4, and DOT5.1 brake fluid standards used in most modern vehicles.
✓ Clear Visual Indicators: Equipped with 5 LED indicators or a clear LCD display that shows real-time moisture content and brake fluid condition. 3-color backlight changes based on measured results for easy interpretation.
✓ Audible & Visual Alarm: Automatic light and sound alarm when moisture content exceeds safe levels, ensuring you never miss a required brake fluid replacement.
✓ Extremely Easy to Use: Simply press the power button, insert the probe into the brake fluid reservoir, and get accurate results in just 3-5 seconds. No specialized training required.
✓ Portable & Convenient: Compact size with a built-in clip design for easy carrying in a tool bag, glove box, or pocket. Perfect for on-site inspections and mobile mechanics.
✓ Energy-Saving Design: Automatically shuts off after 5 minutes of inactivity to preserve battery life.
✓ AC Pulse Testing Technology: Reduces polarization phenomenon during testing, ensuring more consistent and reliable results compared to traditional testing methods.
| LED Indicator Color | Moisture Content | Recommended Action |
|---|---|---|
| Green | < 1.5% H₂O | Brake fluid is good, no action needed. |
| Yellow/Amber | 1.5% - 3% H₂O | Brake fluid is acceptable for now, plan to replace within 6 months. |
| Red (with audible alarm) | > 3% H₂O | Dangerously high moisture content. Replace brake fluid immediately to restore safe braking performance. |
