Universal, the automatic tester for testing the water content in the brake fluid is a universal product that can be used for a variety of fluid types, especially for the brake fluids DOT 3/4/5. The most common original brake fluid for cars is DOT4+. The tester is therefore also ideal for testing the moisture content of brake fluids for trucks, motorcycles and other machinery.
Precise and reliable. With this reliable brake fluid tester, you can check the quality of your brake fluid in any situation. Thanks to the precise measurement with 5 LED indicators, you can be sure that you get an accurate measurement of the water level in the brake fluid. Depending on the specification, the moisture content of the brake fluid can be between 0% and over 3%.
Fast and effective. The brake fluid tester works immediately, checks the quality of the fluid and delivers a finished result in the form of an LED colour display. The Quick Brake Fluid Quality Test measures the water content of the brake fluid to assess the safety of your vehicle. You don't have to wait long for a finished read. The result appears only a few seconds after immersing the pen in the liquid.
Durable and compact. The brake fluid test pen is made of high-quality plastic, very robust and durable in use. This allows the tester to check the water level in the brake fluid multiple times and will prove itself as a helpful car gadget many times. Its compact dimensions (height 15 cm and width 2 cm) make the tester a practical car tool.
Clear reading of the results. A special LED light system on the brake fluid tester shows a clear and clear result that can be read with the help of three LED colours. A green light and a level of 0% means that the brake fluid is of good quality and does not need to be replaced. A yellow LED light between 1 and 2% means that the water content in the brake fluid is normal.
