Coating Thickness Gauges

Accurately measure paint, plating, anodizing, and other coating thicknesses on metal substrates with professional-grade gauges from BRK.

Essential for quality control, surface finishing verification and compliance with industry coating specifications.

  • Ferrous & Non-Ferrous Measurement: Gauges measure coatings on both steel (magnetic induction) and aluminum or other non-ferrous metals (eddy current) — many models auto-detect the substrate type.
  • Paint & Powder Coating QC: Verify coating thickness uniformity on automotive bodies, industrial equipment, architectural metalwork, and consumer products against specification tolerances.
  • Plating & Anodizing: Measure electroplated, galvanized, chrome, zinc, and anodized layer thicknesses for compliance with ASTM, ISO, and customer specs.
  • Fast, Non-Destructive Testing: Instant readings without scratching or damaging the surface — suitable for 100% inspection on production lines or spot-checking in the field.
  • Portable & Easy to Use: Compact handheld designs with digital displays, memory storage, and statistical functions for efficient batch inspection and reporting.

From automotive finishing and aerospace coatings to galvanizing lines and custom fabrication shops, BRK coating thickness gauges deliver the precision and speed quality professionals depend on.
