The BGS Technic 74420 Brake Fluid Tester is a compact electronic testing tool designed for the quick and easy detection of water content (H₂O) in brake fluid. It is suitable for automotive workshops, garages, service centres and vehicle maintenance applications.
The desired brake-fluid standard can be selected by holding the ON/OFF button. After switching on the tester, simply immerse the sensors into the brake fluid and read the result directly from the device. The test result is immediately displayed using coloured LED indicators, allowing quick assessment of the brake fluid condition.
The tester is suitable for DOT3, DOT4, DOT5.1, ENV4 and ENV6 brake fluids. Its break-resistant and acid-resistant plastic housing is designed for workshop use. The convenient pen-shaped design with a pocket clip makes it easy to carry and use during vehicle servicing. A protective cap is included to protect the sensor area when the tester is not in use.
