LUTIFIX AS501 Brake Fluid Tester 2.8in
Price evolution
Product description
The LUTIFIX AS501 is a handheld brake fluid tester that gives quick water-content readings for workshop checks and DIY maintenance. It uses a pressure-boost circuit and an algorithm trained on thousands of points to deliver consistent measurements for common brake fluids, making routine inspections faster and more reliable.
Key features
The AS501 supports DOT3 DOT4 DOT5 DOT5.1 ENV-4 and ENV-6, plus most synthetic blends, so you can test a wide range of vehicles without guesswork. The 260 mm goose-neck probe reaches recessed reservoirs with ease, and the stainless steel sheath resists oil and corrosion. A crisp backlit 2.8-inch LCD ensures results remain legible in bright sunlight or dim garage light. For quick checks, simply dip the probe into the fluid and read the water-content percentage on screen. Note that readings reflect the tester algorithm and are for diagnostic use according to the manufacturer.

How to use it
Turn the unit on and select the fluid type if required, then insert the probe into the reservoir until the sensor is submerged. Read the water-content percentage on the backlit display and compare it with service limits you use in your workshop. If you prioritise quick, repeatable checks the AS501 helps you decide whether fluid needs replacing or further lab testing. It’s a good fit if you want a compact tester that handles multiple fluid types and offers straightforward readings.
Care & maintenance
Wipe the probe clean after each use and avoid prolonged exposure to strong solvents. Store the tester in a dry place and replace batteries when the display dims to preserve measurement consistency. Regular cleaning of the probe sheath will extend the tool’s working life.
