The discovery that accurate temperature measurements are many times difficult in electrical applications of thermography can be a hard pill to swallow. Electrical apparatus are often made from metal that’s bare, so emissivity is low, and thus temperature measurements are unreliable.
The good news is that despite this fact, electrical anomalies can be relatively easy to [...]
Regardless if you’re inspecting buildings, roofs, or electrical or mechanical apparatus, when you have an abundance of air movement across a surface, there is an increase in heat loss or gain on that surface from convective cooling or heating.
Convective cooling is often discussed in many applications of thermography. Often the result is cooling of anomalous [...]
This time we’re finishing up our discussion of thermal diffusivity before moving on to further discussion of thermodynamics. Hopefully taking these topics a step at a time is doing its job and will allow you to absorb the knowledge more easily, and hold onto it longer.
In The Snell Group’s Level I course, we see several [...]
We’re going to explore some principles of thermodynamics in three, smaller blog installments because, like the old riddle suggests, you eat an elephant one bite at a [...]
Even in applications where qualitative analysis is utilized, most reports include temperatures. For comparison purposes it’s advisable to measure a point of comparison, or reference, for the anomalous finding. In electrical applications, we generally advise comparing an adjacent phase of the same apparatus under similar load and environmental conditions. For mechanical applications it may be [...]
As a conscientious maintenance professional, you no doubt take pride in your equipment. As such, you take the proper actions to make sure your tools are in tip-top shape. Your camera is no different. You make sure to keep it secure in its case when you transport it, you protect it from dirt, moisture, harsh [...]
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
The choices in the infrared camera market extend beyond just camera features like resolution, Bluetooth capability and storage card size. These days the market of infrared camera accessories is a separate category in its own right. Additional lenses are among the most popular choices for addition to your basic thermal imaging camera platform, but does [...]
One of the most widely used features added to cameras in recent years is the “auto” button or “auto range” setting. In “auto mode,” or with the touch of the “auto button,” your imager will automatically adjust the level and span setting to account for the warmest and coolest items in the field of view [...]
