FNIRSI CTG-20 Coating Thickness Gauge for Paint Inspection
The FNIRSI CTG-20 Coating Thickness Gauge helps you inspect suitable coatings on supported metal surfaces. It provides a numerical thickness reading without scraping away the finish, making it useful for comparative checks during inspection.
For automotive workshops, detailers, technicians, and vehicle buyers in Pakistan, coating measurements can add useful information to a visual assessment. Record readings from several locations to build a clearer picture of the surface being examined.
Compare Paint Thickness Across Vehicle Panels
Take measurements at multiple points on a compatible panel rather than relying on one reading. Differences can identify areas that deserve closer inspection.
However, a thickness reading alone does not prove accident damage or establish whether paint is factory-original. Consider panel material, previous refinishing, surface condition, and other inspection findings together.
Check Surface Compatibility
This instrument is intended for suitable coating-and-metal combinations. Confirm that both the coating and underlying substrate are supported before testing.
Do not assume it can measure paint on plastic bumpers, glass, wood, or composite panels. These surfaces require a measurement method appropriate to their construction.
Applications of the FNIRSI CTG-20 Coating Thickness Gauge
- Comparing paint thickness on compatible vehicle panels.
- Workshop coating inspection.
- Checking refinished metal surfaces.
- Recording coating measurements during maintenance.
- Educational measurement demonstrations.
Consistent preparation and technique help make comparisons more useful. Use the same approach across the areas you are inspecting.
Preparing for Measurement
Clean the test area and make sure the probe can sit correctly against the surface. Follow the manual’s calibration procedure using appropriate reference materials.
Place the probe perpendicular to the test surface without dragging it. Repeat measurements where necessary and record the location alongside each result.
Curved edges, rough finishes, small measurement areas, and nearby magnetic fields can affect readings. Choose a suitable test location and assess unusual results before drawing conclusions.
