Product Overview

The FLIR GF77 Uncooled Optical Gas Imaging Camera is an innovative, affordable solution designed to detect methane and a range of industrial gases without the complexity and cost of a cooled detector system. As FLIR’s first uncooled OGI camera, the GF77 delivers powerful gas detection and thermal imaging in one rugged, portable design — making it the ideal tool for energy, utility, and environmental inspection professionals.

Built with FLIR’s advanced thermal imaging technology, the GF77 provides clear gas visualization, precise temperature measurement, and versatile lens options to identify leaks and assess thermal anomalies across multiple applications. The result is improved safety, reduced emissions, and enhanced operational efficiency.

Key Features

• Uncooled Detector Design: Compact, cost-effective camera with long operating life and minimal maintenance requirements.
• Gas Detection Capability: Detects methane (CH₄), sulfur hexafluoride (SF₆), ammonia (NH₃), ethylene, propane, and other industrial gases.
• High-Resolution Thermal Imaging: 320 × 240 (76,800 pixels) infrared detector delivers sharp, accurate visuals for gas leak identification.
• Interchangeable Lens Options: Optional lens filters expand capability to detect different gases for multi-industry use.
• Thermal Sensitivity: < 25 mK (0.025 °C) at 30 °C allows detection of subtle gas plumes and small thermal variations.
• Dual-Use Functionality: Performs both gas imaging and standard thermal inspections for electrical, mechanical, and building systems.
• On-Camera Analysis: Integrated measurement tools for temperature and gas visualization with automatic plume enhancement.
• Rugged and Portable Design: IP54-rated housing, ergonomic grip, and 4" color touchscreen for field use.
• Connectivity and Data Sharing: Built-in Wi-Fi, Bluetooth, and FLIR Ignite™ cloud integration for seamless data transfer and reporting.
• Long Battery Life: Operates up to 4 hours continuously on a rechargeable Li-ion battery — ideal for field inspections.
