Flir C2 or Flir E4: Which One’s the Thermal Imaging Keeper?

In the past several years, we’ve slowly shifted from using analog test devices to using more sophisticated, modern, multipurpose digital ones. And this holds true for most test devices available on today’s market, which includes thermal imaging cameras, also known as infrared cameras. Infrared cameras or thermal imaging cameras are a measurement and test device that’s used for measuring temperatures from a safer, longer distance. They’re used in many different industries including the electrical, food and manufacturing industry.

As their name implies, thermal cameras are used to check and help regulate the temperature of electrical devices by monitoring their radiant heating, electrical circuits and pipes, so that they can determine potential infiltration and leaks. Regardless whether you work in the electrical, manufacturing or food industry, a thermal camera is a must have.

There are hundreds of thermal cameras on the market, and they all have different features, advantages, and disadvantages. In this article, I’ll compare the FLIR C2 camera and the FLIR E4 camera. These two are considered intermediate range cameras and can be used in many industrial and commercial settings to test equipment. Let’s take a look at all their unique features.
