Infrared Thermography Certification - Level 2The Level 2 Infrared Thermography Certification course, educates thermographers in the application and practices required to attain Level 2 Thermography certification.
This course meets or exceeds the recommended training requirements of ASNT-TC-1A & ISO 18436-7 for Level 2 Thermal / Infrared Certification. The course is 4.5 days in duration meeting the recommended 35 - 40 hours of formal training as proposed. The course is a good mixture of audio, visual, and kinetic presentation material. Consideration is given to active thermography and the theory related to it. We will also examine the costs associated with lost energy by radiation and the savings available with retrofit. Certification will be granted to students who successfully complete the written requirements. Class size is limited to give maximum interaction between instructor and students. Students are recommended to supply their own Thermography equipment, if the student doesn't have access to their own thermography equipment there will be systems available throughout the week.
