Infrared Thermography

Time recommended for this class: 4 days (customizable)

The course in Infrared Thermography is broken down into four basic components: detailed discussion on the Physics Course, detailed discussion on the Operating Course, Advanced Application Course, and Program Development. Specifically, this course includes instruction and demonstrations with hands-on activities.

Note: a local field trip into customer’s facility is recommended and encouraged to enhance IR learning.
