🚗 Portable Brake‐Fluid Tester Pen for DOT 3 / DOT 4 / DOT5.1
Description
This compact brake‑fluid testing pen quickly detects moisture levels inside your vehicle’s brake fluid by checking fluid conductivity. Clear LED lights tell you whether your brake fluid is safe to use or needs replacement, helping you avoid risky braking problems whether you are a DIY car‑owner or professional repair worker.
Features
✅ Accurate 5‑LED Indicator System
Five colored LED lights clearly display the water‑content percentage inside brake fluid. Green light means the brake fluid is in good condition; yellow signals 1‑3% water content and future re‑check is recommended; red alerts over‑3% moisture which requires immediate fluid replacement. It precisely judges boiling‑point changes caused by water and prevents degraded braking performance.
✅ Broad Compatibility
This moisture analyzer perfectly works with DOT‑3, DOT‑4 and DOT5.1 standard brake fluid. It fits daily passenger cars and vehicles used in auto repair shops for both home‑use maintenance and professional servicing jobs.
✅ Super‑Simple One‑Button Operation
Just press the power‑on button and dip the metal probes into the brake‑fluid reservoir for 1 second, then you will get your test result right away. Press the button again to manually power‑off, or the tester will shut‑down automatically after 15 seconds of inactivity to save battery power.
✅ Pocket‑Sized Portable Design
Made into pen‑style shape with a clip on the side. You can slip it into your jeans pocket or tool bag conveniently. It runs on one AAA‑1.5‑V battery (battery not included), which is easy for you to prepare.
❤️Keep Your Driving Safe
Excess water lowers brake‑fluid boiling point and leads to brake‑failure risks. This tester helps you catch hidden issues early. Timely fluid replacement protects you and your passengers on the road.
