1. Instructions for use: brake fluid moisture tester pen by detecting changes in conductivity to measure the water content in the brake fluid, high water content will reduce the boiling point, affecting brake performance
2. The sensor has high sensitivity and fast response to provide more stable measurement
3. After measuring a fluid, be sure to clean the probe thoroughly so as not to affect the subsequent measurements
4. Sound and light alarm: when the value of 2-3 percent or greater than 3 percent, the buzzer sounds
5. Lightweight and compact pen clip design, easy to carry
6. Data retention function: when measuring, long press the function switch button to keep the data
7. When there is a low voltage indicator, please replace the battery in time
8. Automatic shutdown: after powering on, if there is no signal or no operation for about 5 minutes, the tester will automatically shut down to prolong the battery life
9. Automotive brake fluid test: before testing, make sure the metal probe is clean. Fully immerse the metal part of the probe in the liquid for 3 seconds. Once the display stabilizes, observe the status to read the measured value
10. Power supply: 2 x 1.5V AAA batteries (not included in delivery)
11. Dimensions: 204 x 24 x 30mm
12. Weight: about 58g
