🚗 Brake Fluid Tester Pen
Check your brake fluid moisture levels anytime with this portable LED brake fluid tester—an essential tool for safe car maintenance!
👍 Premium Materials
Our brake fluid tester features a nylon housing, which offers superior corrosion resistance compared to ABS plastic. Brake fluid is known to be highly corrosive; if an ABS housing were used, the plastic would corrode and dissolve upon contact, leading to damage over time. Our product completely avoids this issue.
🛠️ How to Use
1️⃣ Press the button to turn on the brake fluid tester. The green light should illuminate. If it does not, the battery may need to be replaced.
2️⃣ Unscrew the brake fluid reservoir cap and remove the cap from the tester.
3️⃣ Dip the test probes into the brake fluid; the LED lights will indicate the water content percentage.
4️⃣ After testing, remember to securely tighten the brake fluid reservoir cap.
5️⃣ The tester will automatically turn off after 12 seconds of inactivity.
✨High Precision Moisture Detection
- Dual metal precision probe accurately measures conductivity changes to identify brake fluid water contamination
- Excess water reduces brake fluid boiling point, causes brake fade and failure, directly threatening driving safety
- Fast instant reading, just immerse the probe into brake fluid to get results, no complex setup
- Clear LED light grading, directly judge brake fluid health status without extra tools
📝Easy to read
