YW-791 is a testing device that determines whether the brake fluid needs to be replaced by detecting the water content in the brake fluid. It can be used to detect brake fluid DOT3, DOT4 and DOT5.1. Suitable for most vehicles. Multiple Oil type detection with high sensitivity sensor.
Why We Need It?
The brake pressure is transmitted by the brake fluid. Once there is too much water in the brake fluid, pressure transmission will no longer work. Therefore, for driving safety, we need to regularly check the proportion of water in the brake fluid to ensure that you are driving in a safe state.

Features:
Flexible 360° rotating probe
YW-791 uses a metal serpentine tube with a length of 200mm to connect the probe, which is convenient for users to flexibly adjust the direction of the probe when testing needs.
Sound and light dual alarm
When the water content of the tested brake fluid is greater than 3.0% or greater than 4.0%, the backlight (flashing) and the buzzer will alarm simultaneously, prompting the user to replace the brake fluid.
Button buzzer function
When the user performs a valid key operation, the instrument will beep along with it. This function can help users identify whether the current operation is effective.
High-definition backlit screen
Even in places with poor light, users can clearly read the test results.
