Test Pen, Car Brake Oil Tester, 5 LED Lights Display, Oil Quality Testing Tool,

Brake Fluid Tester:
· A digital brake fluid tester suitable for checking the quality of brake fluid in car.
· Developed for professional use in automotive repair shops and in servicing.
· 5 LEDs to indicate percentage of water in the brake fluid.
· Operated by a LR03 AAA 1.5V battery.
· Attention !
· ✔ Replace battery if the green LED not light up any longer after you press power on button . Wash the test probe with tap water after every use.
· ✔ Do not expose brake fluid to the atmosphere for a long time as the fluid is highly hygroscopic!
· ✔ In case of skin contact with brake fluid, thoroughly wash the affected skin or clothing with water.
Indicator Description:
1.5 LEDs indicating the water % in the brake fluid:
2.0% light indicates that the battery is OK, no replacement
3.1% light indicates that moisture content of brake oil less than 1% , brake fluid has a good performance, and ease of use.
4.2% light indicates that moisture content of brake oil less than 2%, brake fluid can be continued to use
5.3% light indicates that moisture content of brake oil less than 3% , proposed to replace brake fluid.
6.4% light indicates that moisture content of brake oil less than 4%, brake fluid should be replaced immediately.
The above data is for reference only

What is Brake Fluid? Why Need to Check and Change the Brake Fluid?
· Brake Fluid, also known as hydraulic fluid, is responsible for moving the various components of your vehicle's braking system.
Brake fluid is a non-compressible substance that lies within the brake lines, delivering the force created by your push on the brake pedal to each of the brake rotors on the four corners of your vehicle. This applies pressure to the wheels and ultimately slows or stops your movement.
The fluid operates under high temperatures and high pressure and, without it, your car or truck would not be able to stop when you push the brake pedal inside your vehicle.
· Over time, brake fluid can absorb moisture from the air, which will cause the fluid to degrade and not work properly. This is why it is important to periodically check the oil fluid and drain it out and replace it with new fluid to ensure proper brake fluid function. That's also why we recommend this Brake Oil Detection Pen to you.
· Regular inspection, replace oil fluid when the red light of the tester is on.
The brake oil detection pen measures the moisture content of
brake oil based on changes in electrical conductivity. It clearly
displays the degree of moisture content through light-emitting
diodes. High moisture content can lead to a decrease in boiling
point and affect braking performance.
