【Wide Compatibility】This 12V Brake Fluid Tester is compatible with DOT-3, DOT-4, DOT-5.1, and most synthetic brake fluids, a good tool to monitor brake oil condition by detecting the water content in the brake fluid, and helps you determine whether the brake fluid needs to be replaced.
【Moisture Content Test】Indicates [ OK ] when the water content is between 0%-2%, [ ! ] when the water content is between 2%-3%, and [ X ] when it is higher than 3%.
【2.8" LCD Display & Sensitive Probe】Come with a large 2.8-inch high-definition LCD screen and a sensitive probe with a 26cm/10.2 inches flexible hose, able to rotate 180 degrees to do easy testing work.
【Attention】The probe should be wiped clean before each measurement and the operation temperature must be between -10°C~60°C. Insert the batteries (4 x 1.5V AAA batteries), paying attention to the correct polarity.
【5-Minute Auto Shutdown】 If you accidentally forget to turn off the detector, you don't have to worry about running out of power the next time you use it, because the detector will automatically shut down after 5 minutes of no operation.
