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.
1: The brake fluid tester is suitable for checking the car brake oil quality
2: 5LEDs to indicate percentage of moisture in the brake fluid and with more accurately result.
3:Insert the tester into reservoir for a second , then the results will be indicated correctly by LEDs.
4: High quality to testing DOT 3, DOT4, DOT5 brake fluid
5: Automatically power off, it Supports 1 LR03 AAA battery (not included)
LED Indicator Display:
1.The green LED lights means water content in the brake fluid H2O <1.5%, brake fluid qualified
2.The yellow LED lights means brake fluid water content H2O = 1.5% to 3%, can continue to use, test again six months later
3.The red LED lights means water content in the brake fluid H2O> 3%, can not continue to use, the brake fluid needs to be replaced
4.LED red flashing means battery replacement
5.LED yellow means low moisture content, check again in six months
6.LED green means 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.
package included: 1x Car brake fluid oil tester detection pen
