The Importance of Getting Your Level 1 Thermographer Certification

Although most infrared thermal imagers are now designed for a one-handed point-and-shoot operation and the operational basics are fairly easy to learn, many owners only learn a fraction of the capabilities and features. More importantly, the frequency of capturing a meaningless image, or incorrectly interpreting an image is a serious concern when the imager is in the hands of an untrained operator. Thermal Imagers are purchased as an investment and are expected to be used to discover problem areas, monitor processes, increase quality, etc.

In order to make that investment hold its value, getting your Level 1 Thermographer’s Certification is an important first step in the process.  To gain complete return on investment in thermography, it is vital to be certified so you can take appropriate images, as well as fully understand what your thermal images are telling you.  Having the equipment and not completely understanding it’s proper use could cause costly mistakes and disrupt your career.  Certification can be an added costly line item to you, but it should be considered an investment that typically yields great returns.

Furthermore, ISO requirements lead many organizations to pursue training based on guidelines and standards from independent organizations such as the American Society for Nondestructive Testing (ASNT) in the United States. The most valuable course will meet or exceed ASNT’s SNT-TC-1A and CP-105 guidelines, by covering the principles and technologies involved and giving you some level of practical training under the direction of a an ASNT-certified instructor.

Listed below are the core concepts covered in a Level 1 Thermography course:

Understanding temperature, mercury thermometers, thermocouples

Optical pyrometers and pyrometer selection

Understanding heat conduction, convection and radiation

Introduction to the founding fathers: Newton, Planck, Kirchhoff and Wien

Material properties of wood, glass, metal, plastic, ceramic/stone

Object size and distance: Field of view, effect of angle, and effects from background radiation

Surface texture: smooth, rough, polished

Emissivity error at temperatures and wavelengths

Applications and the evolution from spot measurements to lines to areas

Infrared camera, spot radiometers and line scanner basics

Introduction to standards

When choosing quality training, you are going to want to make sure your instructor is ASNT-certified with an advanced academic degree and extensive experience in the industry and the field.
