FLIR GF77

Optical Gas Imaging Camera

Gas Find IR

The FLIR GF77 is a groundbreaking uncooled optical gas imaging (OGI) camera with interchangeable lens options, capable of detecting methane, sulphur hexafluoride (SF₆), ethylene, ammonia, and other gas emissions.

Designed for both gas detection and radiometric temperature measurement, the GF77 is ideal for use in electric power utilities, oil and gas operations, chemical and manufacturing facilities, the food and agriculture sector, and by emergency services.

This cost-effective solution features built-in thermographic calibrations and offers the flexibility to detect a wide range of gases simply by swapping lenses.

Each GF77 camera purchase includes a three-month subscription to FLIR Thermal Studio Pro and FLIR Route Creator.
