In a previous ITC Hot Spot we discussed the impact that Thermal Capacitance has on thermographers. Now, this first video in a series of segments that we’re producing on image quality, we address focus and how it can negatively affect our ability to discern important thermal details and measure accurate temperatures if not adjusted properly:
Thermal imaging is a valuable tool for the restoration contractor, allowing them to locate problems and possibly avoid destructive remediation work. The ability to detect and pinpoint damage quickly can also help minimize the scope of work required, saving the client both time and money.
This complimentary paper, originally presented at InfraMation 2008, explains one such use of the technology by a restoration contractor that also includes a special encounter with a certain “resident” of a house that you’ll enjoy reading about.
Over the next several months we’ll be offering a number of additional free InfraMation-related resources for thermographers as ITC gets ready for the 2015 InfraMation conference in Nashville, Tennessee May 11-14. Look for conference papers such as this one, live webcasts of past conference presentations and special registration offers!

Level III student Gabe Peer of Travis Electric Company in Nashville, TN recently sent his instructor, Ron Lucier, a set of images he took of a disconnect on a roof unit. It turns out disconnects on 10 of the 11 units present on this particular roof contained some kind of nest!
Which begs the question…any guesses on what emissivity to use if your fuses are covered with a wasps’ nest? Does it even matter? All joking aside, I know that a number of thermographers out there have had similar, less-than-pleasant, encounters with wildlife while in the field. As if dealing with PPE isn’t enough to worry about, from insects, to rodents to reptiles there’s always the potential for a nice surprise to jump out at us from under an electrical cover.
So, for our readers, curious what you have encountered? Anything that you would like to share? Please feel free to comment below or send in your best story with images and/or video and we’ll post it too.
InfraMation 2015 is now less than a year away and there’s no time like the present to seriously consider sharing your expertise on the issues facing today’s thermography professionals. Clinics, presentations, and poster sessions all originate with you so FLIR and ITC are calling for your papers now for InfraMation 2015.
We are thrilled to be bringing the conference to the heart of Music City in Nashville, Tennessee. Along with the opportunity to help others succeed in building diagnostics and condition monitoring infrared, those with valuable insight into optical gas imaging and research and science thermography, are strongly encouraged to participate!
If you haven’t submitted an abstract before, then I hope you’ll do so this year. Here are just some of the benefits of being a presenter or instructor at InfraMation:
Qualify for a deeply discounted conference registration fee and/or honorarium
Identify yourself as an infrared thermal imaging expert in your field
Earn valuable certification renewal credits
Whatever your thermal imaging know-how, there’s an interested audience at InfraMation. From building investigations to electrical and mechanical monitoring to R&D and OGI to thermography program management and marketing, attendees are always riveted and appreciative.
ITC instructor Ron Lucier is back with another great post, one that I can certainly relate to having recently moved from an old house that once had similar moisture issues. Yes, they can be fun to renovate, but older homes are not for everyone, especially when a lot a scraping and painting (or worse) is involved. Here’s Ron’s take on something that he recently dealt with at his house which also includes a couple of infrared images and some thermal science that our building thermographers should enjoy:
Renovating older homes can be fun. Or not. One thing for sure is they are full of surprises and expensive!
I own a horse farm and the house was built in 1910. Not sure when the porch was added but I noticed the other day that it is the only section of the house that doesn’t have rain gutters (ugh!). I also noticed that one section has paint that was peeling while the other areas of the fascia did not.
An inspection with my T650sc was in order. Yes, I am hung up on the grey scale and in the first image I used a blue interval isotherm. I have water damage:
Heat capacitance, the ability of a material to store thermal energy, often affects what we see with an infrared camera. While this property of matter is what makes some IR applications possible, it can also hide more critical issues that a thermographer may dismiss, or simply miss, if they don't understand the science behind what is happening.
This course is a more advanced introductory course in thermography and serves as an excellent, and recommended, addition to the infrared camera basics and infrared basics courses. Thermography involves more than just learning how to use an infrared camera. IR science, heat transfer, thermal tuning, and application knowledge are all essential subjects a thermographer must understand in order to properly interpret an image. This course is FREE.
This course will give the learner the basic information to understand these concepts.
