Infrared Courses


The following infrared application classes and webinars are offered by The Snell Group.  Please see our Infrared Course Schedule for a list of available dates and times.

On-site Training

All Infrared Courses listed below can be administered for one set price as a customized on-site training class at your location.  There are many advantages to hosting an onsite including:

  • A lower total training cost for groups with six or more participants.
  • The ability to integrate hands-on field work with your plant’s equipment.
  • A lower student to teacher ratio, maximizing the attendees learning experience.

To receive a quote on a customized on-site training class, please contact us, or call us at 1.800.636.9820 (toll-free in the US and Canada) or at +1.802.229.9820.
