    Buildings

    • 0 Comments
    For those of us that don’t frequently inspect buildings with infrared, it may seem at first glance to be an easy job. However, thermographers must take care to interpret misleading patterns thoroughly; taking into account how thermodynamics influence...

    Blank Check

    • 0 Comments
    Sometimes during the early stages of a program development, the question will come up; how valuable is an infrared program? You may hear individuals ask, “Do we really need it and the hassle that goes with it?” I was working as a new thermagrapher...

    Mechanical Routes Not Just Infrared

    • 0 Comments
    As a beginner infrared tech, one is often very fixated on the thermal side of the mechanical route. Which is great, but as an “outsider,” someone of a different department, you have the ability to see things that might be out of place or just...

    Infrared Cameras and Digital Images - The Good, Bad, and Ugly

    • 0 Comments
    The majority of thermal imaging systems have an on-board digital camera. Personally, I think it’s a great addition to IR cameras and many other people do, also. Although this feature is very handy, many of the on-board digital cameras lack one important...

    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...

    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...

    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...
