The FLIR GF346 infrared camera detects and visualizes CO (Carbon Monoxide) and 17 other harmful gases quickly from a safe distance and without the need to interrupt your plant's production process.

The portable camera also greatly improves operator safety, by detecting emissions at a safe distance, and helps to protect the environment by tracing leaks of environmentally harmful gases. CO is an industrial gas with applications in the steel industry and bulk chemicals manufacturing. It is also used for packaging systems for fresh meat and fish.

Additional Info

Carbon monoxide (CO) emissions can be a significant threat to primary steel manufacturing operations and other industries where CO emissions need to be closely watched. Even the slightest leak in a vent stack or pipe can have a devastating effect. To help ensure safety, protect the environment, and protect your investment in your infrastructure, the FLIR GF346 infrared camera enables fast detection of CO emissions.

FLIR GF346 infrared cameras can scan large areas rapidly and pinpoint leaks in real time. They are ideal for monitoring plants that are difficult to reach with contact measurement tools. Literally thousands of components can be scanned per shift without the need to interrupt the process. FLIR GF346 infrared cameras reduce repair downtime and provide verification of the process. And above all, they are exceptionally safe, allowing potentially dangerous leaks to be monitored from several meters away.

Cover the same area as traditional methods in 99% less of the time

​A thermal imaging camera for optical gas imaging visualizes and pinpoints gas leaks without the need to shut down the operation. The portable camera also greatly improves operator safety, by detecting gases at a safe distance, and helps to protect the environment by tracing leaks of environmentally harmful gases.

Using a Gas Detection camera you get a complete picture and can immediately exclude areas that do not need any action. This means you can achieve enormous savings in terms of time and personnel.

Gas sniffers versus thermal imaging cameras

In a complex petrochemical facility there may be many thousands of potential leak paths. Some may be leaking but most will not. Conventional leak detection equipment such as a Volatile Organic Compound meters (or sniffers) mean that the operator must visit and test each potential leak site. Each item must therefore be accessible or made accessible to be tested. Gas sniffers may expose inspectors to invisible and potentially harmful chemicals.

Using gas detection cameras allows the user to examine many potential leak sources in a short time and from a distance.
