Designed for mechanics and DIYers alike, it reports the percentage of water contamination with an accuracy of ±0.3% and a detection window from 0% to 4%. Visual and audible cues make it simple to decide whether fluid is safe, due for replacement, or urgently compromised.\u003c\/p\u003e\n\n\u003ch3\u003eHow does the FT01 tell if brake fluid is safe or needs replacing?\u003c\/h3\u003e\n\u003cp\u003eThe tester measures the electrical properties of brake fluid to estimate water content and displays results with a three-color backlight and buzzer levels.
