Flir C3-X Vs C5: The Ultimate Comparison In 2023


Thermal cameras have become an essential tool for professionals in various industries, including construction, electrical, and mechanical. Flir, a leading manufacturer of thermal cameras, has recently released two new models, the C3-X and C5. In this article, we will compare these two models and help you decide which one is the better fit for your needs.

Design and Build Quality

The C3-X and C5 have a similar design with a rugged, compact body that can withstand harsh environments. However, the C5 has a more ergonomic design with a comfortable grip and a larger display screen, making it easier to use for extended periods.

Thermal Imaging Performance

Both cameras have a thermal resolution of 160×120 pixels and a temperature range of -20°C to 400°C. However, the C5 has a higher thermal sensitivity of 50mK, which means it can detect even the smallest temperature differences. The C5 also has a wider field of view of 54° compared to the C3-X, which has a field of view of 45°.

Visual Camera

The C5 has a built-in visual camera with a resolution of 5MP, which allows you to capture high-quality images and videos. The C3-X, on the other hand, does not have a visual camera, which can be a disadvantage if you need to capture visual details along with thermal imaging.

Measurement Tools

Both cameras have a range of measurement tools, including spot meters, area boxes, and isotherm alarms. However, the C5 has a more advanced measurement feature called FLIR Ignite, which allows you to create custom reports and share them instantly with your team.

Battery Life

The C5 has a longer battery life of up to 4 hours of continuous use compared to the C3-X, which has a battery life of up to 2 hours. This can be an important factor if you need to use the camera for extended periods without access to a power source.


The C5 is more expensive than the C3-X, but it offers more advanced features and better performance. If you need a thermal camera for professional use and can afford the higher price, the C5 is the better choice.


Both the Flir C3-X and C5 are powerful thermal cameras that offer high-quality thermal imaging performance. However, the C5 has a more advanced feature set, a wider field of view, and a better battery life, making it the better choice for professional use. If you need a thermal camera for occasional use or have a limited budget, the C3-X is still a great option.
