Students in KL, busy preparing reports as part of their Level 1 Thermography course. Taken with a T640.
What priority classification should be used for CUI (corrosion under insulation) thermography inspections? CUI is more difficult to classify than electrical thermography. There are many criteria that affect the likelihood of corrosion, including condition of insulation, operating temperature, and surface protection. To classify the risk based on temperature is normally done as follows*; High between … Read More

There are various types of certification; 1 Training company … Read More
It saddens me that I have to revisit this topic again, but I recently came across a company from the UK that carry out most of their electrical thermography with covers on and doors closed. There were almost no covers removed for inspection (only hinged doors on AHU’s were opened). I was asked to review their work, … Read More
Yet again I am faced with the question “How can I make a thermal imaging camera from a Webcam?” I am often asked this, and in particular if the webcam can be converted to work as a thermal imaging camera. The answer to this is that you cannot make a true thermal imaging camera from a webcam. … Read More
Is there a difference between a bad aluminium and copper connections (everything else being equal?) Yes, aluminium and copper and different materials with different properties, and this can have an affect of the failure mode of a connection. Copper has a melting point of about 1050°C, whereas aluminium melts at about 660°C. This is a … Read More
