刹车油检测笔是用于检测制动液的品质，制动液含水量百分比的检测结果由测试笔上5个LED灯的点亮个数来显示。FT123刹车油检测笔根据电导率的变化来测定刹车油的水分变化，通过发光二极管清晰地显示含水分的程度，含水分高会导致沸点降低，影响刹车性能。红光表示刹车油需要更换，绿光表示状态良好，黄光表示状态尚可。
性能特点
功能强大，操作简单；测量准确，使用安全；
检测所有刹车油；具有自动关机功能；
可测试DOT3/4/5刹车油；
According to the change in conductivity to determine the water changes in brake oil, through the light-emitting diode, FT123 clearly shows the degree of moisture, high moisture content will lead to lower boiling point, a ecting the braking performance. Red light means the brake oil needs to be replaced, green light means the oil state is good, and yellow light means the oil state is acceptable.
