Infrared Thermography Training Category 2
Following the recommended training requirements of ISO 18436-7 for Category II Thermal/Infrared Certification, this course is designed to increase the knowledge of the Category 1 Infrared Training to the point where challenges such as active infrared applications may be met. The course looks at infrared radiation from a quantitative view to help determine the monetary value of remedial action taken as a result of Thermographic findings, and draws on a variety of materials to support all learners.
