Configured as a compact, handheld probe, this brake fluid tester identifies moisture levels in DOT 4 fluid to assist in brake system maintenance. A multi-colored LED panel provides clear visual feedback on fluid condition, while the integrated automatic shut-off function preserves the included AAA battery. This reusable tool serves as a more efficient alternative to single-use test strips for frequent fluid inspections.
