Thermography Cat II

The Thermography CAT II Course builds on introductory thermography knowledge and develops the skills needed for more demanding inspections.

Participants explore the relationship between heat transfer, surface properties, camera performance and measurement accuracy. The course focuses on selecting appropriate inspection methods, compensating for measurement influences and evaluating thermal findings in their operating context.

Applications include electrical systems, rotating machinery, process equipment, insulation and building envelopes.
