## Description

2 PCS Car Brake Oil Test Pen, DOT 3 DOT 4 DOT 5 Brake Fluid Content Tester, Brake Diagnostic Inspection Tool with 5 LED Indicators, Universal for Most Cars Check Engine Accessories (Black)

## Features

- Safe Driving: The brake fluid test pen is a tool used to test the quality of car brake fluid. The humidity of the brake fluid will affect its performance and working effect. It can detect moisture changes in the brake fluid in time to ensure the normal operation of the braking system and driving safety.
- Effect: There are 5 LED lights on this test pen, which are green, yellow, and red. The green light indicates that the water content of the brake fluid is low and the brake fluid is qualified. The yellow LED light indicates that the water content of the brake fluid is acceptable and it can continue to be used, but it must be checked again after 6 months. A red LED light indicates that the brake fluid contains high water content and cannot be used anymore, so it should be replaced immediately.
- Easy to Use: Press the switch button and insert the test pen into the water tank. When the moisture content in the brake fluid reaches or exceeds a certain value, the sensor will detect the presence of moisture. Based on the display of the LED light on the pen, you can quickly and qualitatively determine the water content of the brake fluid.
- Product Details: You will get 2 x brake oil test pen, the casing is made of high-quality plastic, matte texture, easy to grip and not easy to slip off. The probe is made of copper and is oil-resistant. No cable connector design, mini and light weight, easy to carry.
- Application: Test tool suitable for most automobiles and can be used to detect the moisture content of DOT3, DOT4, and DOT5 brake fluids. Because the quality or type of brake fluid is different, for testing different types of brake fluid, please wash the test probe with clean water after each use to ensure the accuracy of the results.
