With applications ranging from construction inspections to the study and development of cutting-edge technological components, thermal imaging cameras are strong and widely beneficial instruments. Temperatures and other such parameters that are frequently imperceptible to the human senses alone are revealed by these sensors, together with important contextual information. With the appropriate thermal imaging tool, you and your team may easily and quickly produce evaluations that are more comprehensive and complete. Learn more about thermal imagers, common applications for them, and how to choose the right one for your company's requirements by continuing to read.

Thermal imaging cameras: what are they?

There are other names for thermal imaging cameras, such as thermal imagers, infrared cameras, and thermographic cameras. The goal of these devices is the same, regardless of their many names: to identify temperature fluctuations in a certain region and offer a visual depiction of those variations. The main feature that sets a thermal imager apart from a regular camera is the range of light it can record. While infrared cameras exclusively record infrared radiation, traditional cameras use the visible light spectrum to produce pictures. Thermal imaging cameras provide sight that is not possible with natural methods since infrared is a wavelength that is outside of human visual light.

According to Tech Briefs, everything that is warmer than absolute zero releases infrared radiation, which is one of the main reasons thermal imaging cameras are so successful. The sensitivity of modern thermal imaging equipment allows it to clearly depict temperature variations in a visual manner for users to understand.

What is the purpose of a thermal imaging camera?

Thermal imagers have a wide variety of industrial and commercial uses. At Testo, we provide thermal imaging instruments for a wide variety of use cases, including:

• Building thermography, to detect thermal bridges and defects.
• Building inspection, to identify potential areas of mould contamination, among other tasks.
• Quality assurance, to ensure products leaving the production line are at the expected temperature.
• Research and development, to ensure prototypes and test products stay within a safe temperature range.
• Heating engineering, to ensure heating systems work properly and identify leaks without having to conduct a direct visual inspection.
• Maintenance, to identify preventive maintenance opportunities and reduce the potential for major failures and similar issues.

Thermal imaging cameras have proven themselves useful across the modern economy. Whether it's a widespread need like building HVAC maintenance or highly specialized roles like monitoring the temperature of a prototype circuit board, thermal imagers play a vital role.

What should you look for in a thermal camera?

The standards for thermal cameras vary greatly depending on their intended purpose. In some cases, a basic camera will perform consistently and effectively, such as?in?building inspection and maintenance. In others, higher thermal sensitivity and resolution are required for useful results, such as in research and development. However, there are some basic specifications that every thermal imaging camera should offer:

• Minimum resolution of 160 x?120 pixels.
• Thermal sensitivity less than 120 millikelvins —?meaning visualizations of temperature differences as slight as 0.12 C.
• Intuitive, simple controls.

Other factors to keep in mind aren't related to the operation of the camera itself or the imaging results, but the ease with which such information can be shared with others. Modern thermal imaging tools also offer software that makes analysis and reporting a more streamlined affair.
