Before relatively recent advances in sensor technology, processing power, and hardware integration, thermal imaging was the sort of field-specific solution that only industrial contractors, engineers, or maintenance teams had access to.
The products were generally massive, bookshelf-priced, and oriented toward specific professional environments. That’s less of a fair label to put on the market today, as much of the requisite hardware’s costs have gone down to the point where professional thermal imaging has become a much more amateur-accessible solution.
That’s great news for professionals who want that high degree of diagnostic convenience off the clock and DIY enthusiasts who want a little more detail than a multimeter alone can provide, without the professional price tag.
What to Look for in a Thermal Camera
Just picking up the cheapest thermal camera you can find may not be the most effective buying strategy. The most immediately impactful spec is likely your sensor’s thermal resolution, as a higher-resolution thermal sensor will generally make it easier to spot narrow temperature bands and associated issues.
A clear image can be incredibly important as well, especially on a consumer-oriented model. Software enhancements can make visualizing thermal patterns much easier when examining irregular surfaces or large spaces for issues. And there’s a practical consideration in the viewfinder: a fast refresh rate can make all of those descriptions a lot easier on your eyes, especially as you’re moving around a space to detect overheating electrical components in your house, or irregular heating patterns in a vehicle, property, or other electrical system.
Battery life should be at least a relevant concern in your buying decision because, depending on just how you plan on using your thermal imager, stopping to charge it could cut seriously into your productivity. A portable thermographic imager should at least enable you to tackle a full day of inspections or problem-solving with a reliable view of what’s happening, so you don’t have to fiddle with wires or an adapter all the time.
Where Thermal Imaging Comes in Handy
The chief advantage of a device like this is that it allows you to detect issues that the naked eye might not notice. A property inspector, for example, can look outside windows to see how well the insulation around them is holding, or check the studs around doors and windows for irregular heat patterns.
Heating and cooling professionals can use thermal imaging to find temperature irregularities in walls, and an electrician can instantly see if a fussy electrical connection or component is hotter than the rest of its environment.
The same idea extends to diagnostics and routine maintenance in your vehicle. A thermal imager can find temperature anomalies early in a system malfunction, rather than waiting for a pretty pronounced failure before stepping in. That means you save time and avoid replacing perfectly good components when you come in to address symptoms instead of the root issue.
Pro-Level Performance, Without The Pro-Level Cost
Today’s professional-grade thermal imaging manufacturers are a great survey of how much the category has opened up in recent years. Accumems, in particular, has a line that is both shaped for flexible professionals but also has robust price competition with other much more well-known imager brands. Anyone in the market to compare should at least take a look at what a professional thermal imaging solution has to offer.
The key is choosing according to the way you will work. For more occasional DIY-based inspections or the odd investigation, portability and ease of use are likely to be more significant. If you’re doing a lot of inspection work, then, of course, you will be looking for a bit extra from your imager, so resolution, image detail, update rate, battery operational time and reliability become increasingly important.
