What makes thermography so useful?
There are 3 things that make infrared thermal imaging especially useful:
It is non-contact leak detection and uses remote sensing : Thermography does not affect the target or intrude upon it in any way.
It is two dimensional leak detection – Comparisons between areas on the target are possible : the technician can measure at two points or a hundred points in the same image, and then compare them.
It is in real time leak detection : Immediate action is possible as real time imaging allows for fast scanning of stationary targets.
