Robust and durable design: Unlike cheaper ABS models, this brake fluid tester features a high-strength nylon housing.

This high-quality material offers excellent resistance to impacts, chemicals, and corrosion commonly found in workshop environments. The result: a long service life and proven reliability, even under intensive use. Professional Use & Private Use: This brake fluid moisture tester was developed to meet the needs of automotive workshops, garages, and mechanics, and is also ideal for private vehicle maintenance. Any safety-conscious car owner can check the condition of their brake fluid in seconds without any special technical knowledge, ensuring effective preventative maintenance. Quick and Easy Testing: Thanks to advanced technology, the brake fluid tester analyzes the fluid in seconds. Simply immerse the pen tip into the reservoir or a fluid sample. Within seconds, the LEDs light up and display the result. No complicated calibration or interpretation required: a valuable time saving for a reliable diagnosis.
