Meet the AUTOOL AS501 Brake Fluid Tester

Designed for both professional shops and motivated DIYers, the AS501 takes the guesswork out of brake fluid maintenance. It measures moisture content through conductivity changes and highlights when moisture levels move toward the critical threshold, helping you assess condition and plan maintenance with confidence.

Crystal-clear readability in any environment

The tester features a 1.8-inch HD backlit display that remains legible in bright sunlight or dim workshop corners. Its clear numerals and straightforward layout let you interpret results quickly, whether you are testing a brand-new unit or performing routine service on a customer vehicle.

  • Accurate moisture testing with a fast read in about 10 seconds
  • Wide fluid compatibility covering DOT 3, 4, 5, 5.1 and related fluids

Durable probe for ongoing reliability

A stainless steel probe provides corrosion resistance and long-term durability, with a flexible design that remains comfortable to handle during repeated tests. The sensor delivers consistent conductivity-based readings that you can trust across repeated use.

  • Stainless steel probe withstands exposure to brake fluid
  • High-sensitivity sensor supports repeatable measurements

Compact, portable, and supported

Powered by two AA batteries, the AS501 is easy to move between vehicles or workstations. AUTOOL backs the tester with a 3-year service and technical support, offering long-term reliability and peace of mind for daily workflows.

In real-world scenarios, you can use the AS501 during routine maintenance, after brake system work, or when evaluating a vehicle before delivery. It translates test data into actionable insights, helping you decide when fluid refreshment or inspection is due without overhauling your process.

FAQ
