Infrared Thermography

Infrared Thermography

Training duration: 1 day

This 32-hour Level I thermography course offers a hybrid learning model. The first 16 hours are done online. The remainder of the course is done in two days of classroom training where infrared theory, heat transfer concepts, and correct operation of thermal imaging equipment are discussed. Participants will learn how to take quality thermal images that are clear, concise, and easy to interpret. Additional discussions will include tested ideas to set up a successful thermal program within your facility or customer locations. The instructor is a Level III Thermographer and provides students with broad field knowledge allowing the learning experience to be interesting, fun, and resourceful. This course includes hands-on activities and real-life examples.
