Product Overview

The FLIR G620 Optical Gas Imaging Camera is a high-performance, uncooled OGI solution designed to detect and visualize hydrocarbon and volatile organic compound (VOC) gas leaks quickly and safely. Engineered with a 640 × 480 infrared detector, exceptional thermal sensitivity, and advanced image processing, the G620 empowers inspectors to identify methane and other gas emissions in industrial environments with precision and reliability.

Ideal for use in oil & gas facilities, refineries, chemical plants, and power generation sites, the G620 combines advanced optical imaging, real-time data capture, and FLIR’s ergonomic design to enhance field inspection efficiency while ensuring compliance with environmental and safety standards.

Key Features

• High-Resolution Gas Imaging: 640 × 480 (307,200 pixels) infrared detector for clear visualization of gas plumes and leaks.
• Accurate Gas Detection: Detects methane (CH₄) and other hydrocarbon gases in the 3.2–3.4 µm spectral range.
• Uncooled Detector Design: Maintenance-free system optimized for reliability, portability, and lower cost of ownership.
• High Thermal Sensitivity: < 30 mK (0.03 °C) at 30 °C enables accurate detection of very small gas leaks.
• On-Camera Analysis: Provides real-time measurement tools for quick leak identification and reporting.
• Wide Temperature Range: Measures temperatures from –20 °C to +350 °C (–4 °F to +662 °F).
• Connectivity & Data Sharing: Integrated Wi-Fi, Bluetooth, and FLIR Ignite™ cloud upload for immediate image sharing and documentation.
• Rugged & Ergonomic Design: Built for industrial use with IP54 protection, drop resistance, and an intuitive 4″ touchscreen interface.
• Flexible Optics: Supports multiple lens options (24°, 14°) to match inspection distances and field-of-view needs.
• Quantitative Data Logging: Capture thermal and visual data for inspection reporting and regulatory documentation.
