FLIR G343

Optical Gas Imaging (OGI) Camera for Carbon Dioxide (CO₂)

The FLIR G343 is an innovative Optical Gas Imaging (OGI) camera used to visualize possible carbon dioxide (CO₂) gas leaks in complex systems including enhanced oil recovery, carbon capture systems, and hydrogen-cooled power generators. Whether or not CO₂ is a byproduct of a production process or used as a trace gas, the portable, non-contact G343 is ideal for detecting CO₂ gas leaks without interfering or shutting down large-scale manufacturing operations.
Superior gas visualization

The G343 uses FLIR’s patented High-Sensitivity Mode (HSM), which makes CO₂ leaks stand out more clearly while allowing you to efficiently scan thousands of components and with 1-Touch Level/Span, you can auto-adjust the level and span of your image with a single touch

Built-in Wi-Fi and Bluetooth® allow you to connect to smartphones or tablets and effortlessly edit and store images in the cloud, or wirelessly transfer files using the included FLIR Ignite™ cloud service

Comfortably operate and interact with your G343 thanks to its rotating 10.16 cm (4 in) LCD touchscreen, which allows you view targets from any direction
