Every target surface that you point your infrared camera at has a surface characteristic of emissivity. How’s your comfort level with that subject? I talked about this a little in blog #015 (Radiosity! What is it?) As you might remember, … Continue reading
Review Blog #060 & #061 and continue with the exercise. (Warm wall cavity areas (lighter color) and wood framing (darker color): #5 scenario: viewed from the outside during the cooling season (summer) – Are the bays insulated? #6 scenario: … Continue reading
Review Blog #060 and continue with the exercise. Cool wall cavity areas (darker color) and warmer wood framing (lighter color): Scenario #3 – viewed from the outside during the heating season (winter) – is the wall insulated? Scenario #4 – … Continue reading
To answer that question we have to ask “Why do people choose to get a home inspection before buying a house?” It’s to reduce the “RISK” factor. The greater the investment, the greater the risk! So, a trained home inspector … Continue reading
Are you comfortable when you are asked to perform a moisture investigation on a “roof”? Roofs are notorious for water leaks and highly expensive to repair. An infrared camera is a great tool for pointing us in the right direction … Continue reading
The question comes up sometimes about the reflectivity of glass, since it has a high emissivity of .92. If the emissivity is .92 the reflectivity is .08. So why can I see my infrared reflection when pointing my infrared camera … Continue reading
Want to hear a discussion about the science surrounding the use of infrared cameras for building envelope applications and moisture investigations? Want to better understand the feature differences in Fluke cameras and the justification for price differences? Want to get some hands-on … Continue reading
Blog #055 – Your THERMOGRAPHY COMFORT LEVEL – Three modes of Heat Transfer. Think on a molecular level.
To be comfortable in using an infrared camera you must be very familiar with the three modes of heat transfer: conduction, convection, and thermal radiation. I’ll use the glossary of the ASNT Nondestructive Testing HANDBOOK, Volume 3 Infrared and Thermal … Continue reading
To be comfortable in using an infrared camera you need to be familiar with two types of heat transfer and three modes of heat transfer. I’ll talk about the three modes of heat transfer (conduction, convection and radiation) in a … Continue reading
When you point your IR camera at a surface, infrared energy waves are flooding into the detectors. Some of the waves are a result of the emissivity of the material. Some of the IR waves coming into your infrared camera … Continue reading
