Coating Thickness Gage – Precise Layer Measurement for Quality Assurance
A Coating Thickness Gage is a compact, high-accuracy instrument used to measure the thickness of coatings, paints, platings, or anodized layers applied to metal or non-metal substrates. This essential tool ensures that coatings meet quality and performance specifications, helping prevent issues like premature failure, corrosion, or product rejection.
Available in magnetic induction, eddy current, or ultrasonic technologies, coating thickness gages are designed for both ferrous and non-ferrous materials. Whether handheld or benchtop, these gages offer fast, non-destructive testing with digital readouts and real-time data recording.
Key Features of Coating Thickness Gage
Accurate Thickness Measurement
Ensures accurate thickness readings on both magnetic and non-magnetic surfaces.
Digital Display for Quick Readings
Easy-to-read screen shows instant and reliable results.
Non-Destructive Testing
Measures without damaging the coating or substrate.
Portable and User-Friendly
Compact, handheld design ideal for field or lab use.
Applications of Coating Thickness Gage
- Automotive Paint Inspection & Quality Control
- Aerospace Component Coating Verification
- Galvanizing, Plating & Anodizing Thickness Checks
- Pipeline & Structural Steel Corrosion Protection
- Marine & Shipyard Painting Validation
How to Use a Coating Thickness Gage
- Select the Substrate Type: Choose “Ferrous” or “Non-Ferrous” based on the base material.
- Calibration: Use calibration foils and zero plates to ensure accurate readings.
- Place the Probe: Gently position the probe perpendicular to the coated surface.
- Read Measurement: The coating thickness is instantly displayed on the screen.
- Record & Analyze: Store individual readings or use batch mode for average thickness reports.
