Level II Thermography

Curriculum of Infrared Thermography Level 2 Course

The Level 2 course is designed to increase the knowledge of the Level 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 meets or exceeds the recommended training requirements of ASNT-TC-1A for Level II Thermal/Infrared Certification. The course is a good mixture of audio, visual, and kinetic presentation material to help enable all types of learners to benefit from the material presented.
