Why you need this tester Protects safety and equipment by giving a clear, numeric readout of water content and oil condition. Early detection prevents brake failure, hydraulic contamination, and costly downtime. Fast, reliable results let technicians and vehicle owners make confident decisions on fluid replacement or maintenance. Key benefits Clear numeric water-content display with automatic alarm when contamination is too high — reduces guesswork and increases safety. Supports detection of a variety of oil types, so one instrument works across automotive and industrial fluids. Durable metal probe delivers accurate, repeatable measurements and resists corrosion for long service life. Three-color backlit screen provides immediate visual feedback by automatically matching the backlight to the measured content, speeding up pass/warn/fail decisions. Built-in energy saving: the instrument automatically shuts down after about 5 minutes of inactivity to preserve battery life. Features and performance Numeric readout: precise water content and oil-condition values for clear records and troubleshooting. Automatic alarm: audible and/or visual alert triggers when water or contamination levels exceed safe thresholds. Metal probe: high-precision, corrosion-resistant construction for accurate measurements and extended durability. Three-color backlit display: instant visual assessment without needing to interpret raw numbers alone. Auto power-off: saves energy and ensures the meter is ready when you need it. Compatibility and form Supports multiple oil types and commonly encountered fluids — use one instrument for brake fluids, hydraulic oils, and other oils listed in the product documentation. Built for field use and routine inspections; probe and display are designed for repeated handheld operation and quick checks. Practical use scenarios Vehicle brake service: verify brake fluid water content during routine maintenance to determine if flushing or replacement is needed before braking performance is compromised. Fleet and commercial vehicle inspections: rapidly screen multiple vehicles for contaminated brake or hydraulic fluids to prioritize repairs and reduce downtime. Industrial equipment maintenance: check hydraulic and lubrication systems for water contamination to prevent component wear and system failure. What you get for your time and money Faster, more accurate fluid assessments compared with visual inspection or guesswork. Reduced risk of equipment damage and improved safety through early, reliable detection. One tool capable of testing several oil types, lowering the need for multiple instruments. Note: Follow the product documentation for supported oil types, measurement procedures, and alarm threshold settings to ensure correct use and interpretation of results.
