Detect Gas Leaks at Substations and More

The FLIR GF77 is a groundbreaking uncooled optical gas imaging camera with interchangeable lens options that detect methane, sulfur hexafluoride (SF6), ethylene, ammonia, and other gas emissions. Capable of both gas detection and radiometric temperature measurement for thermal inspections, the GF77 is ideal for electric power utilities, oil and natural gas operations, chemical/manufacturing facilities, the food and agriculture industry, and first responders. This affordable solution offers the benefit of built-in thermographic calibrations and the flexibility to detect a wide range of gases by simply changing lenses. The purchase of a GF77 camera includes a 3-month subscription to FLIR Thermal Studio Pro and FLIR Route Creator.

A Versatile Solution for Gas Detection and Thermal Inspection
Safely locate gas leaks and perform accurate thermal inspections using one camera.
From laser-assisted autofocus to 1-Touch Level/Span contrast enhancement, the GF77 offers the latest high-tech features while remaining affordable.
Work easier with the ergonomic design, tools to organize findings in the field such as GPS, Wi-Fi, and annotation, plus rapid-reporting capabilities.

Mejore la claridad de la imagen y la detección de gas con las funciones avanzadas de Flir

La GF77 está calibrada para la temperatura, por lo que puede ajustar el contraste entre la nube de gas y el fondo. O aumente el contraste instantáneamente con la característica de ajuste automático 1-Touch Level/Span. Por último, resalte el movimiento de la pluma de gas con el modo de alta sensibilidad de FLIR (HSM).
