Brake fluid detection pen is based on the change in conductivity to determine the moisture change brake fluid. It shows clearly the extent of moisture contained by the light-emitting diode, high moisture content will lead to lower boiling point, affect braking performance. Red indicates the brake fluid need to immediate replacement, green represents good condition, yellow indicates the status is acceptable but soon need to replace.
It is with Digital LCD Detection Display screen.
Heavy pressure is pressure measurement, light pressure is deflation.
Tire pressure protection, Kpa / Psi / Bar pressure units can be selected by switch button.
The tester can check the car brake oil quality and tire pressure test, high precise and portable 2 IN 1 tester.
3 LED lights display the percentage of moisture content in the brake fluid, Testing DOT 3, DOT4, DOT5 brake fluid.
Product Size: 15.5x2x2.6cm
Battery: 1 x CR1220 button battery (not included).
1.Green LED light: Water content 0%,the tester start normally, The brake fluid performance is good, there is no water in brake fluid.
2.Yellow LED light: Water content
3.Red LED light: Water content>3%,the brake fluid need to be replace immediately.
After testing the moisture content of the brake fluid, please clean the metal probe with water to prevent corrosion.
When measuring tire pressure, the display shows OL indicating that the test pressure range is exceeded. Press the valve at the time of inspection, otherwise it will deflate.
