FLIR G346

Optical Gas Imaging (OGI) Camera for Carbon Monoxide (CO)

The FLIR G346 is an innovative Optical Gas Imaging (OGI) camera used to detect carbon monoxide (CO), nitrous oxide (N₂O) and other dangerous and environmentally harmful gases in steel plants and industrial manufacturing facilities. CO emissions can be a significant threat to primary steel manufacturing operations. Even the slightest leak in a vent stack or pipe can have a devastating effect. With the portable, non-contact FLIR G346, inspectors can scan large areas at safe distances without interfering or shutting down production and manufacturing operations.
Superior gas visualization

The FLIR G346 accurately measures temperatures from -20°C to 300°C (-4°F to 482°F) in real time, and FLIR’s patented High-Sensitivity Mode (HSM) makes CO leaks stand out more clearly while allowing you to efficiently scan thousands of components

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 a rotating 10.16 cm (4 in) LCD touchscreen which allows you view targets from any direction
