6 Introduction
6.1 FLIR GF77
The FLIR GF77 is an uncooled infrared camera that both visualizes gas emissions and measures temperature accurately to diagnose electrical
and mechanical faults. The FLIR GF77 features multiple swappable lens options, LR and HR which are spectrally filtered from 7-8.5 and 9.5-12 μm respectively,
to visualize gases of interest and are easily interchangeable in the field. You can scan components quickly, focusing on problem
areas and finding small leaks that you might miss with a traditional TVA (Toxic Vapor Analyzer) or “sniffer”.
Efficient leak detection and repair (LDAR) will help protect the environment while avoiding product losses and ensuring a
safer work environment.
- Industrial plants.
- Renewable energy producers.
- Natural gas power plants.
- Locations along the natural gas supply chain.
- Liquid natural gas (LNG) terminals and storage.
- Power and utility industry for SF6 and CH4 gas.
- Chemical industry for ethylene and other compounds.
- Food and Agriculture industry for ammonia.
- First responder market for all above.
- Temperature measurement inspections for all of the above.
The FLIR GF77 is ideal for:
6.1.1 Key features
-
Gas-specific spectral filtering
Use the LR lens for visualizing CH4, N2O, C3H8, SO2, R-134a, and R-152a.
Use the HR lens for visualizing SF6, NH3, and C2H4 (ethylene). -
Combined gas and temperature measuring features
Perform your gas leak survey as well as thermography inspection using the same lens while also choosing the right temperature range for your environment.
-
One-touch contrast enhancement
A quick tap on the screen automatically improves the contrast between the gas and the background scene.
-
Accentuated plume movement
Easily toggle on/off High Sensitivity Mode (HSM) to highlight plume movement for increased gas detectability.
-
Award-winning ergonomic design
Based on the FLIR T-series platform, the FLIR GF77 offers a 180° rotating optical block, vibrant touchscreen LCD, and eyepiece for ease of use in direct sunlight.
-
Streamlined reporting features
Organize your findings in the field using the built-in voice annotation, GPS tagging, customizable work folders, and Wi-Fi connections for video streaming or sharing.
