Thermal imaging cameras are an invaluable tool for tradespeople and contractors. It allows them to quickly and safely detect leakages and identify construction problems.
However, not all thermal cameras are created equal. Here are a few basic features to look out for to ensure you maximise your return when purchasing a thermal imaging camera.
Display size and image quality
A large, vibrant and easy-to-understand display is one of the most important factors in choosing a thermal imaging camera.
A high-resolution display coupled with a wide field of view allows users to cover a greater area more quickly, while still taking precise and accurate measurements. This can greatly improve productivity on the job
A minimum recommendation for a thermal imaging camera display is 3.5 inches. Other models offer a 4-inch screen, and this can be a great investment if you plan on using the device to cover larger areas.
Thermal sensitivity also plays a major role in deciding on purchasing a thermal imaging camera. A device that has a higher level of thermal sensitivity will be capable of showing more significant thermal contrast, even in areas where there are only minor differences in temperature.
Thermal sensitivity is typically measured in Noise Equivalent Temperature Difference (NETD), which is expressed in terms of Millikelvin. Cameras with a lower NETD rating will deliver a better image, that is easier to understand.
Durability and ease of use
Usability is the final cornerstone in determining which thermal camera to purchase. You want a device that is intuitive and easy to use but is also durable and capable of standing up to any hazardous environments it may be exposed to when utilised.
This is one area where there is simply no compromise for quality. It may require you to invest a little more for a superior thermal imaging camera, but it will pay off in the long run, as It's long-term reliability and accuracy will outlast a cheaper model.
