The Teledyne FLIR GF77 Gas Find Uncooled IR Thermal Imaging Camera can be used to detect methane (CH4), sulphur hexafluoride (SF6), ethylene (C2H4) and ammonia (NH3) leaks (lens dependent). This decreases or eradicates the downtime for conduct repairs, increases productivity, reduces any potential loss of earnings, and ensures that all workers are kept safe.

The FLIR GF77 Gas Find Uncooled IR Thermal Imaging Camera can be used to inspect industrial and natural gas plants, as well as points along the gas supply chain, and liquified natural gas terminals and storage units. This instrument is also of particular use to renewable energy producers.

Applications of the FLIR GF77 Gas Find Uncooled IR Thermal Imaging Camera vary depending on the lenses purchased with it. There are two types of lenses available: 

  • LR: low-range lenses have a spectral range of 7 to 8.5µm making them suitable for detecting methane, nitrous oxide, propane, sulphur dioxide, R-134a, and R-152a
  • HR: high-range lenses have a spectral range of 9.5 to 12µm making them suitable for detecting sulphur hexafluoride, ammonia, and ethylene

Please see the table below for further information regarding which lenses are supplied with each option.

This ergonomic IR camera with extensive reporting features is specifically optimised for detecting gases; it is able to detect and trace small leaks that are often missed by traditional TVAs or ‘sniffers’. For a quick introduction to FLIR GF77 Camera, please see the following video.

Thermal Technology

The FLIR GF77 Gas Find Uncooled IR Thermal Imaging Camera features an IR resolution of 320 x 240-pixels and is equipped with laser-assisted autofocus for accurately establishing the target area.  

False negatives occurring because gases have been absorbed into other wavelengths are prevented as the FLIR GF77's lenses ensure it is spectrally filtered for specific gases. This means that the FLIR GF77 Gas Find Uncooled IR Thermal Imaging Camera can be used to scan components and trace gas emissions to their sources more effectively, thereby ensuring that repairs can be conducted efficiently. This works to reduce the amount of downtime required to conduct necessary repairs whilst simultaneously improving the safety of the workforce.

Additionally, the FLIR GF77 Gas Find Uncooled IR Thermal Imaging Camera can be set to High-sensitivity Mode (HSM), a video processing technique that highlights plume movements and thereby increases gas detectability.

Further to this, the FLIR GF77 Gas Find Uncooled IR Thermal Imaging Camera is also equipped with a Viewfinder function allowing the user to continue to trace gas in bright conditions.

The user can view thermal footage (and therefore the detected gases) via the FLIR GF77 Gas Find Uncooled IR Thermal Imaging Camera’s 4-inch LCD display. Using the 1-Touch Level/ Span feature the user can improve the contrast between the background scene and the detected gas. Moreover, this instrument features six colour palettes (Iron, Grey, Rainbow, Arctic, Lava, and Rainbow HC) and four imaging modes, allowing the user to tailor the FLIR GF77 Gas Find Uncooled IR Thermal Imaging Camera to suit the application. It includes the following imaging modes:

  • Infrared
  • Visual: view digital images captured using the integrated 5MP visible-light camera with an integrated LED photo/ video lamp
  • MSX®: digital images are overlaid onto IR images to improve the clarity and detail of the thermal picture
  • Picture-in-Picture: view a particular point on the image in greater detail without losing the overall field-of-view

Furthermore, the FLIR GF77 Gas Find Uncooled IR Thermal Imaging Camera features an integrated Area Measurement Tool for determining tank levels and volumes. This thermal camera is also METERLiNK/ Bluetooth enabled allowing it to interface with a headset and external sensors, improving the ease and comprehensiveness with which inspections can be performed.

Reports

In addition to a METERLiNK/ Bluetooth interface, the FLIR GF77 Gas Find Uncooled IR Thermal Imaging Camera features a Wi-Fi interface allowing the user to share and stream thermal footage. This proves useful when making collaborative decisions and allows the operator to transfer the data required to create comprehensive reports.

The FLIR GF77 Gas Find Uncooled IR Thermal Imaging Camera also features a Drag-and-Drop feature for generating reports.

Thermal data can be saved to the FLIR GF77 Gas Find Uncooled IR Thermal Imaging Camera’s removable 8GB SD card. This camera also features customisable work folders, GPS tagging and a voice annotation feature for managing and organising thermal footage.

Ergonomic Design

The FLIR GF77 Gas Find Uncooled IR Thermal Imaging Camera’s responsive, graphic interface and scratch-resistant touchscreen facilitates quick, easy access to the required features and settings without lagging.

The physical design of the FLIR GF77 Gas Find Uncooled IR Thermal Imaging Camera is based on FLIR’s award-winning T-series. It is optimised to be comfortable- and easy-to-use over prolonged periods of time and in various light conditions. To this end, it includes a 180° rotating optical block and an eyepiece designed for use in direct sunlight.

The Teledyne FLIR GF77 Gas Find Uncooled IR Thermal Imaging Camera is a cost-effective, comprehensive and customisable visible and infrared camera. It is ideal for protecting workers and ensuring the continuation of production by detecting gas leaks before significant damage is incurred.
