Brake Fluid Liquid Tester Pen With 5 LED Vehicle Diagnostic Tool For DOT3/DOT4
Why do we need Brake fluid tester pen ?
The dangerous ofa bad quality Braike fluid :
1. The inferior brake fluid causes the brake failure easily,thereby lead to a accident
2. The Brake fluid is related to the life of Brade pads, if doesn't take it seriously, the life of brake pads is worried.
Brake fluid tester description :
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 needs immediate replacement, green represents good condition, yellow indicates the state is acceptable but soon replaced.
1.check the car brake oil quality
2.5 LED lights display the percentage of moisture content in brake fluid,how the test results more accurate
3.Press the button for power on, green LED will light up.
4.Insert the tester into reservoir for a second , then the results will be indicated correctly by LEDs.
5.Testing for DOT 3, DOT4, DOT5 brake fluid
6.Auto power off, Supports 1 LR03 AAA batteries (not included)
LED Indicator Display:
1.The green LED lights = water content in the brake fluid H2O <1.5%, brake fluid qualified
2.The yellow LED lights = brake fluid water content H2O = 1.5% to 3%, can continue to use, test again six months later
3.The red LED lights = water content in the brake fluid H2O> 3%, can not continue to use the brake fluid needs to be replaced
Red LED: change brake fluid
4.LED red flashing: battery replacement
5.LED yellow: low moisture content, check again in six months
6.LED green: brake fluid lines / cell row
Green: Battery OK, that is, brake fluid does not contain water
Green / yellow: brake oil in water content of less than 1%, better brake fluid performance, ease of use.
Green / yellow / yellow: brake oil in water content of about 2%, brake fluid can continue to use.
Green / yellow / yellow / red: brake oil in water content of about 3%, the proposed replacement of brake fluid.
Green / yellow / yellow / red / red: brake oil in water content of at least 4%, the brake fluid must be replaced immediately responsible for very dangerous.
