Selecting the right infrared thermal scanner can seem overwhelming if you’ve never shopped for one before. Nonetheless, it does not need to be a complex matter. With a little guidance you can confidently choose a thermal scanner that fits your budget, your needs, and your workflow. Here’s how.
Start with resolution and accuracy
One of the first things to check when shopping for an infrared thermal scanner is its resolution and temperature accuracy. The resolution (number of pixels per inch) is higher (say 320×240 or 640×480) the more detail you will see on the thermal image. It implies more accurate hot-spots, diagnostics, and reduced false alarms. Also ensure the device has a good temperature measurement range and accuracy specs as you want the thermal scanner to reliably measure what matters for your situation.
Consider the field of view and focus
A thermal scanner with a wide field of view lets you scan larger areas quickly. That comes in handy in a facility inspection, the building envelope or equipment diagnostics. However, when you are providing detailed work such as checking circuit boards, electrical connections, etc. then a narrow field of view with a tight focus is preferred. Also check whether the thermal scanner has manual or automatic focus, and whether the lens is interchangeable or fixed.
Think about environmental and usage conditions
Do you have an indoor or outdoor scanner you are going to, in sunshine or shade? In a dirty factory or in a sterile lab? These factors matter. Look for a thermal scanner with appropriate ingress protection (IP) rating, rugged housing, and the ability to handle ambient temperature variation. Also, when you will be scanning moving objects or objects that vary in temperature fast, it is better to use a device with higher frame rate (such as 60 Hz) instead of the one with lower frame rate (such as 9 Hz).
Check connectivity and workflow features
Modern thermal scanners often include features such as built-in WiFi, Bluetooth, and apps for mobile viewing and reporting. That will save you time in case you are used to generating inspection reports or exchanging pictures with teammates. Ask yourself: will the thermal scanner integrate easily into your existing workflow? Is the software intuitive? Will it help you save hours either on field reporting or data analysis?
Evaluate support, calibration and long-term cost
Buying the initial infrared thermal scanner is only part of the investment. Take into account the calibration requirements, warranty, the support and availability of spare parts. A scanner of an established brand with good support will usually be rewarded with reliability and comfort. Spending a little more in the present will buy you some peace and less down the line surprises.
Match the scanner to your application
Lastly, do not be misled into features that you will not use. When you are performing periodic building envelope inspections, you might not require a high quality equipment that is designed to inspect industrial electrical equipment. Select your main purpose building inspection, HVAC, mechanical, electrical or scientific work and customize your budget and features accordingly. A well-matched thermal scanner will serve you better than an over-specified one you rarely use.
Conclusion
Choosing the right infrared thermal scanner means balancing resolution, field of view, durability, connectivity and support, all with your specific application in mind. You will save frustration, money and time wastage when you invest the time to make the right choice.
