Coating Thickness Gauges

Understanding Coating Measurement Instruments

Coating thickness gauges are precision devices designed to measure the depth of non-conductive or conductive coatings applied to base materials. These instruments operate using distinct physical principles depending on substrate characteristics and coating composition.

Key Product Types Available from Enviro Test Construct

• Magnetic induction gauges used for measuring non-magnetic coatings on ferrous substrates such as structural steel
• Eddy current gauges designed for non-conductive coatings on non-ferrous metals including aluminum and copper
• Ultrasonic thickness gauges capable of measuring coating thickness on non-metallic substrates such as plastics and composites
• Combined probes integrating multiple measurement principles for versatile field applications across varied materials
• Benchtop and laboratory-grade systems for controlled environment testing requiring higher precision and repeatability

Each type supports different inspection scenarios, and selection depends on substrate type, coating material, and required accuracy.
