Product Overview

The FLIR Gx620 Optical Gas Imaging Camera is a premium-grade OGI solution engineered for detecting and quantifying gas leaks in industrial and energy-sector applications. With a 640 × 480 cooled infrared detector, the Gx620 provides superior image resolution and thermal sensitivity, making it ideal for locating hydrocarbon, methane (CH₄), and volatile organic compound (VOC) emissions quickly and accurately.

Built for professionals working in refineries, petrochemical plants, gas processing facilities, and power generation, the Gx620 combines high-resolution imaging, on-camera quantification analytics, and FLIR Ignite™ cloud connectivity to enhance inspection efficiency, safety, and compliance with environmental standards.

Key Features

• High-Resolution Gas Imaging: 640 × 480 (307,200 pixels) cooled infrared detector captures detailed and precise gas leak visuals.
• Gas Quantification Capability: Integrated analytics provide real-time leak rate estimation directly on the camera.
• Broad Gas Detection Range: Detects hydrocarbon gases, methane, and VOCs using a specialized mid-wave infrared spectral range (approx. 3.2–3.4 µm).
• Exceptional Thermal Sensitivity: < 20 mK (0.02 °C) enables clear visualization of the smallest gas plumes, even at long distances.
• Rugged Field Design: IP54-rated and certified for hazardous environments (ATEX/IECEx compliant) to ensure safety in industrial zones.
• Ergonomic and Flexible Operation: Rotating 4″ touchscreen and built-in viewfinder provide easy use in bright outdoor conditions.
• Connectivity and Reporting: Integrated Wi-Fi, Bluetooth, and FLIR Ignite™ cloud access allow instant image sharing, data storage, and team collaboration.
• Interchangeable Lenses: Available in multiple focal lengths (e.g., 14.5°, 24°) for both close-up and long-range inspections.
• Quantitative Analysis: Automatically calculates estimated leak size and emission rate for fast documentation and reporting.
• Rugged Portability: Designed for field reliability, with a durable chassis and long battery life for extended inspections.
