Vision Tests and Thermography

The onset of presbyopia can have an impact on your ability to perform high quality thermographic [...]

What Kind of Hot is It?

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 [...]

Transformer Cooling Tubes

One of the easiest, and often safest, types of electrical apparatus to inspect are oil-filled transformer cooling [...]

Focus First

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 [...]

Infrared Cameras: The Answer my Friend is NOT Blowing in the Wind

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 [...]

A Thermal Success Story

We have several customers that we visit and perform infrared scans for on a regular basis. Recently we were in a textile mill in a state where we’ve been performing inspecting for the past four years.  The equipment list has remained virtually unchanged in the time we’ve been inspecting there. The only variances were during shutdowns for [...]

Imager Lens Care Basics

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 [...]

Are Extra IR Lenses Needed?

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 [...]

The “Auto” Range Feature: Best Friend or Worst Enemy?

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 [...]

Color Palette Choices

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 [...]
