One year ago I made some predictions about where I thought the market might be headed (click here to read full post). It is useful, I think, to see how today’s reality compares with yesterday’s dreams. • A $1,000 imager We are close, but thankfully not yet there. Sales of lower-cost systems continue to grow. This has [...] I seem to have accumulated a short list of items each of which is too small to be a week’s posting by themselves, but all of which I wanted to share with you—thus the title of this week’s posting! First: A follow-up to let you know that the ice on Joe’s Pond here in Vermont finally [...] Last week, I went into detail on tips to help you prepare for a roof inspection by conducting a pre-inspection during daylight hours. Now, I will explain necessary steps to take while inspecting a roof in the evening, and what you can expect to see if there are issues. Before you begin, it is important to [...] Over the past couple of weeks we’ve talked about how low-slope roofs leak, the damage caused by trapped water, and the conditions needed to use thermal imaging to find it in the roof system. Many new thermographers ask me: “How can I safely and reliably get good results up on the roof?” This vertical ladder [...] Last week we talked about how low-slope roofs leak and, as a result, how the water becomes trapped in the roof system—generally in the insulation—accelerating roof failure. According to a survey by the National Roof Contractors’ Association, on average, roofs in the United States are replaced every ten years or less! A penetration to the [...] The snow is nearly melted here in Central Vermont. If you are responsible for the maintenance of those low-slope roofs under which we work and live in, this is a great time to get up on the roof and conduct a spring inspection. A simple walkover with an inspection checklist in hand can [...] Last week we talked about emissivity and reflection, probably the two most talked about issues among thermographers. But that ain’t all we need to talk about! There is a reason engineering heat transfer courses are both long and notoriously challenging. We won’t go that deep into it, but as most of you know, I am [...] This week’s Teaser Infrared Image is a good tie-in, to this week’s post from The Snell Group: Reflecting on Our Surroundings

Spock Answer: This is a thermal image of a polished diamond plate, steel ramp that is facing skyward. It is very [...] Thermographers operate in a different world than all other humans—maybe that explains something about us. Initially, it can be quite intimidating to learn how to Think Thermally™, but most thermographers I’ve known soon find it fun as well as challenging. Even after nearly 30 years of paying attention to the temperature relationships in the world, [...] The work we do as thermographers has immense value; I don’t mean to imply that the world would stop turning without us, but thermographers do a great deal to have it turn more smoothly and efficiently! The disastrous situation in Japan reminds us of how vulnerable the complex systems and machines we have grown to [...] |
