As a Level 2 thermographer you shall provide guidance to category 1 personnel in the areas of equipment selection, techniques, limitations, data analysis, corrective actions and reporting.

After a short introduction to certification levels and procedures, and related standards, you will take an initial test. During the course you will repeat and learn more about thermal science and heat transfer as well as gain advanced knowledge on IR theory and IR equipment. The course ends with a multiple choice exam.

The course includes advanced practical exercises and discussions about the participants’ professional experiences and cases from the field. Thermal and infrared science theory are taught by using formulas, diagrams, and graphs. The focus is on steady-state processes, but transient mechanisms are also included.

Who Should Attend This Course?

This course is designed for thermographers holding a Level 1 certificate, who want to increase their knowledge about IR thermography and want to qualify as a Level 2 certified thermographer.
