Brake Fluid Tester 5 LED Electrolytic Moisture Meter

A brake fluid tester used to check the moisture content in brake fluid quickly and clearly. It works with an electrolytic measuring system, using the probe to read electrical resistance and compare the result against acceptable moisture limits.

Used for routine vehicle maintenance, servicing and fault finding, this tester helps you check brake fluid condition before carrying out brake work or general inspection jobs. Handy for home garage use as well as workshop checks, it gives an immediate reading through a 5 LED display, so you can see straight away whether the fluid needs closer attention. When checking a vehicle before maintenance or keeping on top of regular servicing, it is a straightforward way to monitor a part of the braking system that is often overlooked.

The tester is operated using the built-in switch and probe, keeping the checking process simple without needing complicated setup. An easy calibration check using water allows you to confirm the unit is reading correctly before use, which is useful when carrying out repeated checks across different vehicles. A red LED low battery warning also helps avoid confusion during testing, so you are less likely to mistake weak battery performance for an incorrect reading. For regular garage and workshop use, that makes it a practical tool to keep close to hand for quick condition checks.
