Brake Fluid Tester Mechanic One

The SIXTOL MECHANIC FLUID TESTER ONE is a compact brake fluid tester designed for quick and convenient assessment of water content in brake fluid, helping monitor fluid condition during regular vehicle maintenance. The tester features 5 coloured LED indicators that display approximate water content levels from 0% to around 4%, allowing easy interpretation of brake fluid condition during testing. Compatible with glycol-based DOT 3, DOT 4 and DOT 5.1 brake fluids, the tester is suitable for checking brake fluid in passenger cars and commercial vehicles, but is not intended for silicone-based DOT 5 fluid. The tester features two metal probes and simple one-button operation, allowing users to check brake fluid by immersing the probes into the fluid reservoir and reading the LED indication. The lightweight pen-style design features a practical pocket clip for convenient carrying and storage, while operation requires one 1.5V AAA battery, which is not included in the package.
