●What it Does: The brake fluid test pen is a handheld car testing device used to detect the water content in the brake fluid to determine whether the brake fluid needs to be replaced. Provide you with more accurate detection results, replace brake fluid in time, and improve driving safety.

The probe is made of steel, has excellent oil resistance and waterproofness, is not easy to react with the outside world, and is designed with a cover. Lightweight and easy to carry.
●How to Use: When using, keep the 2 metal probes of the pen tip soaked in brake fluid. Press and hold the button at the end of the pen tip for more than 2 seconds, and read the 5 LED indicators on the pen barrel to get the test result. After the test is completed, the test pen will automatically turn off after 12 seconds.
●LED Indication Instructions: With 5 LED lights, 3 colors. Green (0%), green-yellow (<1%), green-yellow-yellow (1%-2%), green-yellow-yellow-red (2%-4%), it is recommended to replace the brake oil. Green yellow yellow red red (>4%), dangerous, brake fluid must be replaced immediately.
