Level I Thermography

Curriculum of Infrared Thermography Level I Course

The curriculum of Level 1 Infrared Thermography Course suits the needs of ASNT’s designed training module for Level I Thermal / Infrared Certification. The course teaches trainees by conducting audio, visual, and kinetic presentation classes. Each student gains expertise in the operation of infrared thermal equipment and an understanding of its features and specifications.
In conclusion of this course, every trainee must show their abilities, not only in operating their infrared device, but also in accurate temperature measurement, inspection, and data finding. Students can receive the certification only after passing the written exams.
There is a restricted number of students in each class to ensure the best level of interaction between trainer and trainees.
