Spring is (nearly) here!

Last week we talked about emissivity and reflection, probably the two most talked about issues among thermographers. But that ain’t all we need to talk about! There is a reason engineering heat transfer courses are both long and notoriously challenging. We won’t go that deep into it, but as most of you know, I am [...]

Bundle Up Your Overcoats!

Adding more layers of clothing helps us keep warm in the winter by reducing heat transfer. But Frosty seems to do just fine without any additional layers.

In much of the country, including NC and GA where I just spent a couple weeks, the weather is quite “seasonal,” meaning it is getting cold—right on schedule [...]

Emissivity: Understanding How it Affects Your Thermal Images

I often joke that were it not for emissivity, you’d not need training to use an imager! In our courses we find emissivity is the #1 most confusing issue for people, whether they are engineers, home inspectors or new thermographers. In fact, we all usually have a good laugh that many cannot even pronounce the [...]

Radiometric Measurements---How Thermographers Can Measure them Accurately

In life we often make corrections to our first impressions or first courses of action. Whether we are following directions while driving, stepping on the scale to check our weight or adding cream and sugar to our coffee, corrections are an important part of getting it right! Without them, we don’t get to where we [...]

Radiational Heat Transfer: Moving Heat Magically

My recent trip to the beach was a pleasant reminder of the “magic” of radiational heat transfer. How else can we describe warmth delivered from 94 million miles away? We feel similar radiant transfer when we BBQ, sit in front of a fire, or feel a hot brick wall on a cool evening. The truth [...]
