Thermal Imaging Camera for Continuous Gas Leak Detection

Optical gas imaging cameras from FLIR can visualize and pinpoint gas leaks. With an optical gas imaging camera it is easy to continuously scan installations that are in remote areas or in zones that are difficult to access.

Continuous monitoring means that you will immediately see when a dangerous or costly gas leak appears so that immediate action can be taken. Optical gas imaging (OGI) cameras are widely used in industrial settings such as oil refineries, natural gas processing plants, offshore platforms, chemical/ petrochemical industries, and biogas and power generation plants. 

OGI cameras like the FLIR A6604 can detect harmful greenhouse gases that can seriously harm the environment.

Cooled detector makes the smallest temperature differences visible

FLIR A6604 contains a cooled Indium Antimonide (InSb) detector that produces thermal images of 640 x 512 pixels. More pixels give you a wider field of view so that you can monitor larger installations. It also offers an ultra-crisp image.

The high sensitivity mode further enhances the detection level of the camera so that the smallest gas leaks can be detected.

Easy to control

FLIR A6604 is easy to control from a safe distance. It can be fully controlled over Ethernet and easily integrated in a TCP/ IP network. The FLIR A6604 is GigE Vision and GenICam compatible.

FLIR A6604 detects the following gases:

Benzene, Ethanol, Ethylbenzene,Heptane, Hexane, Isoprene, Methanol, MEK, MIBK, Octane, Pentane, 1-Pentene, Toluene, Xylene, Butane, Ethane, Methane, Propane, Ethylene and Propylene.
