Product Details
✓WIDE RANGE OF APPLICATIONS: The automotive brake fluid tester is a universal device for most vehicles. It can check the condition of DOT-3, DOT-4, DOT-5.1 brake fluids as well as most synthetic brake fluids. It is extremely easy for personal use and is widely used for private workshops, repair shops and car dealerships.
✓EASY TO USE: The test procedure is fast and efficient and has a simple control panel. The backlight lights green at 0%-2% data (brake fluid is ready to use). At 2%-3%, the backlight turns yellow and the buzzer sounds slowly (brake fluid needs to be changed). The backlight is red and the buzzer sounds quickly when the data is greater than 3% (brake fluid needs to be changed immediately).
✓EASY READING: high-sensitivity probe + audible alarm, instant display of results, large screen with three-color backlight, easy to read the measurement results whether day or night.
✓FAST DETECTION: the detection process is fast and efficient, the control panel is simple and easy to use. Can quickly determine whether the brake fluid needs to be replaced after the background light reminder.
✓EASY TO CARRY: the case is well structured, compact and fits well in your hand. You can take it with you when traveling without taking up too much space.
