Brake Fluid Tester – Moisture Content LED Indicator
High water content lowers the boiling point and affects braking performance.
Specification
1 – checks the car brake oil quality
2,5 – LED lights display the percentage of moisture content in brake fluid
3 – auto power off
4 – Black Brake fluid tester: 1 LR03 AAA batteries (not included)
Instructions:
This Brake Fluid detection pen measurement is based on change in conductivity, to determine the moisture level in brake fluid.
It shows the level of moisture in the liquid, by a 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 should soon be replaced.
1 – the green LED lights = water content in the brake fluid – H2O <1.5%, brake fluid qualifies
2 – the yellow LED lights = brake fluid water content H2O = 1.5% to 3%, can continue to use, test again in six months
3 – the red LED lights = water content in the brake fluid H2O>3%, do not continue to use the brake fluid, it 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
Features:
Five LED indicators show test results more accurately.
Tests DOT 3, DOT4, DOT5 brake fluid
Press the switch to turn on the power, the green LED light shows battery is OK, the green light will not shine if battery needs to be replaced.
Automatic shutdown.
Technical parameters:
Green: Battery OK, that is, brake fluid does not contain water
Green / yellow: brake oil has water content of less than 1%, good brake fluid performance, can continue to be used.
Green / yellow / yellow: brake oil in water content of about 2%, brake fluid can continue to be used.
Green / yellow / yellow / red: brake oil in water content of about 3%, recommend 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, could be dangerous to continue use.
