Product Overview

The FLIR G304 Optical Gas Imaging (OGI) Camera is purpose-built for the detection of hydrofluorocarbons (HFCs) used in refrigeration, air-conditioning, and chemical-processing systems. Featuring a cooled 320 × 240 infrared detector with a spectral range tuned to HFC absorption wavelengths, the G304 makes invisible refrigerant gas leaks visible — helping maintenance teams quickly locate and repair leaks before they cause energy losses, equipment damage, or environmental harm.

Designed for HVAC, chemical manufacturing, and environmental monitoring, the FLIR G304 provides superior image clarity, high thermal sensitivity, and on-camera quantification capabilities to ensure reliable, safe, and compliant gas-leak detection.

Key Features

• Specialized for HFC Detection: Optimized spectral response (approx. 8.5 µm – 8.9 µm) to visualize refrigerant and hydrofluorocarbon gas emissions.
• High-Resolution Imaging: 320 × 240 (76,800 pixels) cooled infrared detector delivers crisp thermal imagery for accurate leak identification.
• Exceptional Thermal Sensitivity: < 15 mK (0.015 °C) @ 30 °C enables detection of the smallest refrigerant leaks.
• Quantitative Gas Measurement: Built-in analytics estimate leak rates and gas concentration directly on the camera display.
• Real-Time Visualization: Detect leaks instantly across compressors, valves, and piping networks — even during normal operation.
• Rugged & Reliable: IP54-rated housing with 2 m drop resistance for dependable field use in industrial environments.
• 4″ Rotating Touchscreen Display: High-brightness LCD (640 × 480) offers easy navigation and visibility in bright light.
• Wireless Connectivity: Integrated Wi-Fi, Bluetooth, and FLIR Ignite™ cloud connectivity for fast data sharing and secure storage.
• Multi-Lens Options: Interchangeable 14° and 24° field-of-view lenses for short- or long-range inspections.
• Safe, Non-Contact Detection: Detect gas leaks remotely, reducing risk to personnel in pressurized or hazardous areas.
