Whether used in a car workshop or at home in your garage: the easily manageable brake fluid tester BW05 is the perfect measuring device for quickly and precisely determining the water content in a vehicle's brake fluid. The BW05 serves to check the three most important types of brake fluid DOT3, DOT4 and DOT5.1 and, what is more, conceivably easy to use:

Having selected the test mode for the respective type of brake fluid, the sensors of the digital measuring device can be dipped into the fluid. Based on the traffic light principle three colour LEDs indicate the water percentage result in a matter of only a few seconds (see graph): Green light suggests that you are all set and ready to go, since the share of water amounts to less than 1.5 %. Yellow signifies that you may proceed with your journey, but should frequently reexamine the water content that is already between 1.5 and 3 %. And with more than 3 % the red light denotes the immediate necessity of exchanging the brake fluid to prevent a failure of the hydraulic braking system

At the end of the check-up switch the BW05 off, clean the sensors with a dry cloth and store the measuring device in a dry location until it is needed again. Should you forget to switch the device off by hand, no need to worry: the tester switches off automatically after a period of 20 seconds.
