The DY23B brake fluid tester can support 3 brake oil type detection, detect DOT3/DOT4/DOT5.1 brake fluid. Our brake fluid tester is universal fit for most vehicles. Brake pressure was transmited by brake fluid, the pressure transmit will out of function once brake fluid include too water. In order to safe-driving, we must test water ratio scale in brake fluid regularly. The brake fluid tester help us do current maintenance, make sure we drive in safety condition.  【2 Seconds Quick Detect Water Content of Brake Fluid】The brake fluid tester can measure the water content in the brake fluid in 2 seconds to determine whether the brake fluid needs to be replaced. It helps you do regularly brake fluid check, make sure you drive in safety condition.
【Screen Prompt & Sound Alarm】When the water content of the brake fluid reaches 2.5%, an exclamation mark will be displayed on the screen to remind you to change the brake fluid.

Brake fluid tester is equipped with a 250MM long gooseneck probe, which can be bent at will, allowing easy access and flexible testing even in hard-to-reach areas. The probe is covered with chromed surface, which is resistant to oils and oxidation.
 【LCD Display】The brake fluid tester is equipped with a high-definition LCD screen, which can intuitively and clearly display the percentage of brake fluid water content, allowing you to view the test results at a glance. The brake fluid tester is equipped with a backlit button. One key to open, no matter how dark it is, you can read the data clearly.
Operation Steps: 1. Install 1pc 9V(6F22) battery at the back of tester. 2. After inserting the battery, press POWER button to turn on the tester, all analog bars turns off with buzzer sounding, indicates the product self-test is successfully finished. 3. Press DOT3, DOT4, DOT5.1 button to switch brake fluid type to test. 4. Insert the probe into brake fluid, At this moment, the number of analog bars shows the water ratio in the liquid. When the water ratio is more than 3%, the LCD screen backlight will turn red, and the buzzer will alarm that the brake fluid needs to be replaced. 5. Press POWER button to turn off the tester. Note: 1. After use, please clean the probe and avoid any retention of stains that might affect the test. 2. If in use for a long time, best to remove all batteries and store in a dry place at normal room temperature.
