The QBH WT01 brake fluid moisture meter is more than a diagnostic device—it is a professional-grade communication and decision-making tool for modern automotive workshops.
Unlike traditional testers that rely only on LED indicators, the WT01 delivers clear digital readings of brake fluid water content, allowing technicians to visually demonstrate fluid condition to customers and increase service approval rates.
By combining precision moisture detection with an intuitive LCD interface, this tool transforms routine inspections into data-driven maintenance decisions.

Accurate Moisture Analysis for Safer Braking Systems
Brake fluid naturally absorbs moisture over time, which reduces its boiling point and increases the risk of brake fade or failure.
The WT01 is designed to provide fast and reliable brake fluid water content analysis, supporting:
This makes it a versatile brake fluid liquid tester suitable for passenger vehicles, commercial fleets, and industrial equipment.
