Portable Digital Brake Fluid Tester for DOT3 DOT4 DOT5.1 with Flexible Probe

Check your brake fluid condition quickly before maintenance with a digital brake fluid tester designed for fast, accurate moisture readings.

Fast Brake Fluid Moisture Testing

When you want a clearer picture of brake fluid condition, this tester measures moisture from 0-4% with 0.10% resolution and ±0.3% accuracy. The flexible metal hose makes it easier to reach into the reservoir for testing.

Audio-visual alerts, a 3-color backlit LCD, and a buzzer help you read results at a glance. A built-in flashlight, data hold function, low battery indicator, calibration support, and automatic shutdown add convenience during routine vehicle checks.

Use it for brake fluid condition checking, workshop inspection, automotive maintenance, and vehicle safety checks. Clean the probe before and after testing, and immerse the metal probe for 3 seconds.
