Image Fusion

When Fluke IR-fusion® was first launched, I wondered whether or not it would be perceived as just another marketing gimmick, and if not, how well it would be used. Time has proven that few find it gimmicky and most use it very well.

In the field I nearly always use the Full Infrared setting (left) for [...]

Radiometric Temperatures

We’ve spent the past several weeks discussing heat transfer. Radiation is a special mode of transfer because that is the mode by which energy is transferred from surfaces to our imagers.

All of what we see in the thermal image is nearly always based on the amount of radiation emitted from or reflected by the surface. [...]

Heat Transfer by Radiation Part 2

For young children and pets, the first look in a mirror can be very confusing! They may be asking themselves. “Is that real or…?” Most thermographers share a similar exasperation the first time they see a thermal reflection, most commonly from a bright piece of metal. Many go on to understand that reflections are not [...]

“h” or the Convective Heat Transfer Coefficient

When heat transfer occurs in fluids—defined simply as non-solids—the rate and total transfer are governed by several factors, two of which are easily known: temperature difference and area. More challenging to define precisely is “h” or the Convective Heat Transfer Coefficient. This all-important variable is the amalgamation of a number of influences on heat transfer [...]

Learning From Each Other

One of my Thermal Resolutions for 2011 was as follows:
“I’ve learned nearly all I know about thermography from others and have, honestly, barely scratched the surface, so I resolve to learn more from my professional colleagues.”

I was fortunate to visit the home of Sir William Herschel in the Fall of 2010. Here I am [...]

Chip Wade Inspects a Commercial Property

Many of the same principles of a thermal inspection in a home can be applied to a commercial property inspection.  In this video, Chip Wade shows you how you can take your business to the next level by offering commercial property inspections. He spots a problem in a warehouse that is being converted to an [...]

Chip Wade Uncovers Common HVAC Problems

In our fifth video presented by Chip Wade, common problems in a home’s HVAC system are easily unveiled with the use of a thermal imager. Especially in a home that is 100 years old, inefficient vents and ducts are likely to be draining money on your energy bill. Chip spots a couple of problems that can [...]

Episode 4: Chip Wade Inspects for Moisture Damage

In the fourth video of our series, Chip Wade demonstrates how we can use a Fluke TiR1 to inspect for moisture damage on the inside of a home. As he describes, most homes have been repainted several times, and water damage can be easily hidden from the naked eye. Using the thermal imager, a quick [...]

Episode 3: Chip Wade Inspects Building Envelope and Electrical Outlet

In the third video in this series, Chip Wade starts by showing us some easy spots to inspect that might be draining money from your energy bill. First, he inspects the building envelope and points out what appears to be a common problem with insulation. He then goes inside and scans the electrical outlets to [...]

Reflecting on Electromagnetic Radiation

Reflections, no matter what part of the electromagnetic spectrum we are operating in, are part of life. All materials are partially reflective of some wave lengths and none are perfectly reflective.

We are all familiar with mirrors, but watch a baby or a puppy when they are first looking into a mirror and learning how to [...]
