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 so that they can able to gain expertise in operating Infrared Thermal equipment and understanding its features and specifications. On concluding the course, every trainee needs to show their abilities not only in operating their infrared device, but also gaining dexterity in accurate temperature measurement, inspection and data finding. Students can receive the certification only after cracking the written exams. The number of students enrolled in the course are restricted to provide optimum level of interaction between trainer and trainees.
