KINGBOLEN BF200 Brake Fluid Tester — Handheld DOT‑3/DOT‑4/DOT‑5.1 Detector with Backlit LCD & Probe Light

The KINGBOLEN BF200 is a handheld, high-precision brake fluid tester that quickly detects water contamination in DOT-3, DOT-4 and DOT-5.1 fluids so you can know when a fluid change is needed.

The BF200 combines a sensitive probe, backlit digital display and audible alarm in a compact, ergonomic body to make brake fluid checks fast and repeatable. Designed for personal use, fleets and professional workshops, it evaluates common automotive brake fluids and many synthetic blends, reporting contamination levels within seconds. The gooseneck probe and built-in flashlight let you reach hard-to-access reservoirs and visually inspect fluid colour while getting an electronic readout.

How fast and accurate is the BF200 at detecting contaminated brake fluid?

The BF200 uses a high-sensitivity probe and onboard electronics to produce near-instant results on the LCD with a clear audible tone for unsafe readings. It distinguishes contamination commonly associated with water absorption and displays the outcome immediately, reducing guesswork when inspecting brake systems.

• High-resolution backlit screen for quick numeric readouts.
• Audible alarm triggers when water content exceeds safe thresholds.
• Results appear within seconds for efficient multi-vehicle checks.
• Precision probe designed to sense DOT-3, DOT-4 and DOT-5.1 fluids.

Can I use this tester on different vehicles and brake fluid types?

The BF200 is built as a universal hand tester suitable for most passenger cars, light trucks and many workshop applications. It supports standard DOT brake fluids and a wide range of synthetic formulations commonly used across modern vehicles.
