    Alphabet Soup & Safety

    • 0 Comments
    I was in the military for the better part of a decade. Hence, acronyms are something I’ve grown accustomed to, but sometimes their overuse gets downright ridiculous. I had an e-mail from a former student a week ago that was chock full of letters...

    Heat Related Injuries & The Thermographer

    • 0 Comments
    Heat injuries such as heat cramps, heat stress, heat exhaustion, heat stroke, and dehydration are very serious and can often sneak up on thermographers. Often the victim is not aware of how bad of shape they are in until it is too late and they require...

    What do Thermographers and Vampires Have in Common?

    • 0 Comments
    No, this isn’t the first line of a bad joke. Thermographers, like vampires, have a serious aversion to the sun. Thermographers won’t burst in to flame and become a pile of ash, but the effects of the sun can make outdoor inspections extremely...

    Heat Transfer in 3D

    • 0 Comments
    You don’t need special glasses to read this blog. Also, I’m not talking about the kind of 3D you see in a theater. What I’d like to discuss is heat transfer, one of my favorite topics. In our Level I – Thermographic Applications...

    Trailing with Infrared

    • 0 Comments
    During deer season a couple of years ago, a good friend of mine was out in the woods with his longbow and self-made arrows. All of his stuff was self-made; the bow, the arrows, the quiver, the tree stand, and even some of his clothes. He is self-sufficient...

    Reflectivity and Emissivity - Peas and Carrots

    • 0 Comments
    One of the most difficult concepts for most new thermographers to grasp is the relationship between emissivity and reflectivity. Of the many technical inquiries posed to us at The Snell Group, I would wager the majority of them are on this topic. I know...

    Happy Thermographer Feet

    • 0 Comments
    Happy Feet. What a cute movie with singing and tap dancing penguins (my little niece loves the movie). However, I’m not going to be talking about penguins in this blog. Instead, I’m talking about the feet at the end of our legs and keeping...

    What the “Bleep” caused that?

    • 4 Comments
    Few things are more exciting for me than finding a thermal anomaly I have never seen before or one I cannot quickly figure out its cause. Well, there may be a couple other things I find exciting, but those are for a different blog! I have been involved...

    A Look Back at Infrared - What I Wish I had Learned Earlier

    • 0 Comments
    Someone recently asked me, after my 15 years in this technology, what would I have liked to know in the beginning? Infrared was in a sense a novelty in the beginning, a way to do something other bending conduit and pulling wire. I would have liked...

    The Power of Infrared

    • 0 Comments
    I have been an on-site thermographer and currently work as traveling service thermographer. These working methods at first seem to be very different, and in many ways they are. There are also quite a few similar concepts with both. One of the similarities...

    Infrared Report Preparation

    Infrared reports, what should be in them and what should not? If there was a one size fits all answer, life would certainly be easier! But, each type of inspection requires different information to be presented to the customer. To make things easier,...

    Calibration Intervals: How Often?

    • 2 Comments
    Like any other measuring instrument, infrared imagers require periodic calibration. One of the most often asked questions about imager calibration is how often to have it performed. The answer you get will largely depend on who you ask. Ask the representative...

    Electrical Inspections; Don’t Camp Out

    Can “Cold” Indicate an Electrical Fault?

    What Does it Take to Start an Infrared Program?

    • 0 Comments
    I have been asked so many times, “What does it take to startup an IR program?”Surprisingly, I never have the same answer. Not because I am inconsistent, but rather that there is no one correct answer. Each site, plant, or organization is going...
