What to do when tasked with inspecting thermally reflective surfaces?

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, […]

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 […]

Exposing Electrical Panels

Whether it’s high rise office buildings, hospitals, or an industrial facility, the approaches to accomplishing an infrared electrical scan vary as much as the locations.  One universal thread throughout these inspections is the manner in which most electrical maintenance folks expose panels for inspection.

 

Most industrial grade panels have a two part cover but these configurations […]

Introducing the Ti400, Ti300 and Ti200 Advanced Performance Infrared Cameras

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 […]

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 […]

Roof Moisture Inspections

Roof moisture inspections are one of those applications of infrared thermography that many in the industry have heard of, but not so many have attempted.  It’s kind of a niche application, really.  In my decade or so of experience in this industry, I’ve only had the opportunity to be involved in a handful of these […]

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 […]
