DeFelsko

DeFelsko Corporation is an American manufacturer headquartered in Ogdensburg, New York, specializing in non-destructive coating thickness measurement and surface inspection instruments. Founded in 1966, the company is best known for its PosiTector line of gauges, which are used globally wherever protective coatings are applied and inspected on metal, concrete, and composite surfaces.

DeFelsko instruments employ magnetic induction, eddy current, and ultrasonic measurement principles to non-destructively measure the thickness of paints, coatings, and platings across a wide range of substrate materials. Their gauges are routinely specified in corrosion protection programs, industrial painting operations, and formal quality assurance procedures worldwide.

Key Product Lines

• Coating thickness gauges using magnetic induction (ferrous substrates) and eddy current (non-ferrous substrates) measurement
• Surface profile gauges for measuring blast-cleaned anchor patterns and roughness depth
• Dew point and environmental condition meters for coating application control
• Shore hardness durometers and gloss meters for coating quality verification

Industries Served

DeFelsko instruments are used in shipbuilding and marine maintenance, oil and gas pipeline construction, bridge and infrastructure coating inspection, automotive manufacturing, powder coating operations, and aerospace surface finishing.
