Infrared Thermography Level 1

This course prepares you for qualification as a category 1 certified thermographer. You will learn about the basics of infrared, how to operate the camera under different conditions and for various purposes, how to do an appropriate judgement of the measurement situation in the field and identify potential error sources. You will be able to do IR inspections following written guidelines and to report the result of this inspection.

After a short introduction to thermography you will have hands-on training. The theory sections on heat and infrared will provide you with the basic knowledge needed to use the IR camera in the field, and to recognize and interpret thermal patterns. Strong emphasis will be put on the IR measurement techniques and the influence of emissivity and reflectivity on the measurement results. You will train the measurement on real-life lab equipment and you will also learn how and when to use qualitative and quantitative thermography. A short introduction to inspection routines and reporting principles will finalize the lecture. Now you will be well prepared to create a short case study which you will present in front of the class. The course ends with an exam including multiple choice questions and thermogram analysis.The class includes exercises and our trainers work with images, sketches, and simple diagrams to illustrate the theoretical parts in a descriptive way. No prior certification or experience is necessary to attend this course, although ownership of an infrared camera, laptop and software would be beneficial (bring along if possible).​

Through this Certification Course, participants have the opportunity to accrue 5 Continuing Professional Development (CPD) points.

“I wanted to thank Yellotec for presenting the most interesting course / career development programme that I’ve ever attended since finishing my university studies. Tjaart is a captivating and utmost professional course presenter and one of the most knowledgeable subject matter experts I’ve ever met, in any field. Even though our course was probably very basic if judged by industry professionals, even I as a layman could glimpse aspects of the depth of his knowledge when he answered questions posed by the more experienced students. Tjaart is clearly an institution in Thermography as an engineering science and I can tell you the industry is a better place for having him in it. He is truly a ‘scholar and a gentleman’ and I am enriched by having attended a course presented by him.”
