The TM-8819-T3 Through Coating Ultrasonic Thickness Gauge Meter delivers precise, non-destructive measurements through paint, rust, and other coatings without removal. It features a high-resolution 0.01mm/0.001in accuracy, a wide 0.75-300mm measurement range, and a large backlit LCD for reliable performance in industrial environments. Features and Benefits
- Through Coating Measurement Technology - Measure base metal thickness directly through paint, rust, or plastic coatings, saving hours of surface preparation and preventing damage to protective layers.
- High Accuracy and Resolution - Achieves 0.01mm/0.001in resolution for detecting minute material loss, essential for predictive maintenance and quality control inspections.
- Wide Measurement Range (0.75-300mm) - Versatile enough for thin sheet metal, piping, and thick castings, making it a single tool for diverse material testing needs.
- Large Backlit LCD Display - Provides clear, easy-to-read measurements in low-light conditions such as tanks, vessels, or poorly lit manufacturing floors.
- Durable, Ergonomic Design - Built for daily professional use with a robust housing and intuitive button layout for efficient one-handed operation.
- Automatic Probe Zero and V-Path Correction - Ensures measurement accuracy is maintained by compensating for sound velocity in different materials and probe wear. Applications
- Corrosion and Erosion Monitoring - Inspect pipelines, storage tanks, pressure vessels, and structural steel for wall thinning without stripping costly protective coatings.
- Manufacturing Quality Assurance - Verify material thickness on incoming raw stock, machined parts, and finished products to ensure they meet precise engineering specifications.
- Automotive and Aerospace Maintenance - Measure brake rotors, aircraft skins, and engine components for wear and safety compliance during routine servicing.
- DIY and Home Workshop Projects - Perfect for evaluating metal thickness on classic car restoration, boat hulls, or custom fabrication where non-destructive testing is required. Note: This gauge is an excellent choice for DIY enthusiasts and professionals seeking reliable through-coating measurement capability at an accessible price point.
