Level II Thermography

Curriculum of Infrared Thermography Level 2 Course

The Level 2 course increases the knowledge of the Level 1 thermographer. Topics, such as active infrared applications, will no longer be a challenge. The course looks at infrared radiation from a quantitative view to aid in the determination of the monetary value of actions taken as a result of thermographic findings. It meets and/or exceeds the recommended training requirements of ASNT-TC-1A for Level II Thermal/Infrared Certification. To benefit of all types of learners, the course teaches trainees by conducting audio, visual and kinetic presentation classes.
