Paint it Black?
No, this blog isn’t about The Rolling Stones – it’s about the practice of enhancing emissivity in the field. When a thermographer is tasked with inspecting thermally reflective surfaces there are two options. Either accept that the surface doesn’t emit well—and therefore reflects very well—and therefore can’t provide reliable qualitative or quantitative data, [...]
One of the easiest, and often safest, types of electrical apparatus to inspect are oil-filled transformer cooling [...]
If you’ve had Level I Thermographic Applications training course you most likely heard the mantra of “Focus First!” from your instructor, and with good reason! Of all of the camera settings that can be adjusted by the camera operator, focus is by far the most important. Focus is essential to both image quality and temperature [...]
A new generation of tools with next generation performance
This trio of new Fluke infrared cameras is equipped with LaserSharp™Auto Focus. For consistently in-focus images. EVERY.SINGLE.TIME.
Every infrared camera user knows that without an in-focus image temperature measurements may not be accurate and it’s much easier to miss a problem. LaserSharp™Auto Focus tells you exactly where you are focusing. This is point-and-shoot-and-get- it-right every single [...]

Ti125 Thermal Imaging Made Easy
Recently, I had a Level I student ask me a question I’d never heard before. He asked why there were so many palette choices on his infrared camera. Often I’m asked which palette works best, or which my personal preference is. I’d never had anyone ask me why there are so many choices. He went [...]
After years of working with new thermographers in our training classes, I’ve learned a lot about how people learn. First, we never get it right the first time! Don’t worry about making mistakes, in fact, it is important to make them. But it is also equally important to learn from them. In class we let [...]
Last week we discussed how to adjust level and span manually. Sometimes this can lead to a lot of “button pushing!” It is not a big deal – just one of life’s little aggravations. Thankfully, many models of Fluke imagers have a very helpful solution: 1-TIME AUTO ADJUST.
Both images were taken using AUTO adjust. [...]
Last week we discussed how to adjust level and span automatically and when that feature is best used. While using AUTO can be very convenient in many situations, you’ll quickly find times when MANUAL adjustment is essential, either to getting the best image or understanding what you are seeing.
Use AUTO adjust to get “in [...]
I’m all for using the AUTO adjust feature found on most thermal imagers. That said, it does not mean I can turn my brain off! Many new thermographers believe they can just put their system on AUTO and life will be good. Not true.
AUTO adjusts the span of the image to accommodate all three [...]
