Infrared Thermography
Category 2 Course Curriculum

The Category 2 course is designed to increase the knowledge of the Category 1 Thermographer to the end that 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. It follows the recommended training requirements of ISO 18436-7 for Category II Thermal/Infrared Certification. The applies a good mixture of audio, visual, and kinetic presentation material to help enable all types of learners to benefit from the material presented.
