It’s Not That Easy

Ever wonder why magicians never reveal their secrets? It’s because magic, like most things, is easy once you know the trick. When describing thermography in lay terms, it is easy to over emphasize simplicity and forget the source of the true magic behind thermography – the thermographer.

An infrared inspection system consists of infrared imaging equipment, a thermographer, and the knowledge that he/she possesses. Of these three things, the greatest limiting factor in an infrared inspection is the thermographer.

In order to be an effective thermographer, one must be trained in the following:

• Theory and construction of the object or system being inspected
• Infrared theory and heat transfer principles
• Use and operation of infrared imaging equipment
• Non-contact temperature measurement error sources and how to avoid or correct for them
• Site-specific safety requirements and the use of appropriate PPE

In addition to the above, qualified thermographers must also be experienced with inspecting the subject system. When all things are considered, effective thermographers need considerable training and field experience. Making thermography look simple is a true testament to the skills of a professional thermographer.

The next time you hear the dismissive claim that thermography is easy, remember, it is only easy after someone has invested considerable time and effort to learn the art and science of the trade. In a magic show, the magic comes from the magician, not the wand. In thermography, the magic comes from the thermographer.
