Raythink RG600C
Handheld OGI camera for industrial inspection of methane, sulfur dioxide, and refrigerant gases, featuring a 640×512 uncooled VOx sensor, 23 mK NETD, 23°×18° field of view, and a 3.5-inch touchscreen
What Is RG600C and Who It’s For
Raythink RG600C is a handheld optical gas imaging (OGI) camera designed to visualize SF₆, ammonia, ethylene, and other gas leaks using infrared thermal imaging combined with a visible light sensor. The camera supports detection of gases such as methane, sulfur dioxide, and refrigerant gases in industrial environments. RG600C is used by inspection engineers, maintenance teams, and safety specialists in oil and gas, petrochemical facilities, and environmental monitoring operations where non-contact gas detection and on-site inspection are required.

How Raythink RG600С works
The Raythink RG600C handheld OGI camera detects gas leaks by visualizing infrared contrast created as gases absorb background IR radiation. Using its 640×512 uncooled VOx sensor, the camera visualizes gas plumes in real time while simultaneously measuring the temperature of surrounding surfaces. This dual task functionality allows operators to quickly locate leaks and assess thermal conditions without interrupting operations. The integrated touchscreen provides live imaging and parameter control, making on-site inspection fast, safe, and efficient.
Raythink RG600C applications
The RG600C handheld OGI camera is used for industrial inspections and gas leak detection in cold chain storage, oil and gas operations, and petrochemical facilities. It is also applied in emergency response and environmental monitoring tasks.

FAQ
Honest answers to important questions
An OGI camera is a device that visualizes invisible gas leaks using infrared imaging. It detects gas by capturing infrared radiation absorbed at specific wavelengths, displaying gas plumes as a visible contrast in the scene. This allows inspectors to identify gas leaks without direct contact with the source.
OGI cameras use an infrared detector combined with narrow band-pass spectral filters tuned to wavelengths where specific gases absorb infrared radiation. When gas passes in front of a warmer or cooler background, it absorbs part of the IR energy, creating a visible contrast that appears as a moving gas plume on the screen.
No. OGI cameras do not measure gas temperature. Gas has no stable emissivity and constantly mixes with the surrounding air. Temperature measurement in OGI cameras applies only to solid objects and surfaces, such as pipes, valves, tanks, and equipment.
OGI cameras detect gases that absorb infrared radiation within their spectral range. Typical examples include methane and other hydrocarbons, sulfur dioxide, ammonia, and refrigerant gases. The detectable gas list depends on the camera’s spectral filter design.
Some OGI cameras are certified for use in hazardous or explosive environments. These explosion-proof (Ex-rated) models are designed to operate safely in areas with flammable gases, such as oil and gas or petrochemical facilities. Always verify the certification of a specific camera before use in hazardous areas.
OGI cameras can be used in a wide range of environments, depending on the model. Gas visualization relies on infrared contrast with the background, not only on ambient temperature.
Yes. OGI cameras can operate in complete darkness because gas visualization is based on infrared radiation, not visible light. The infrared detector captures thermal radiation from the scene and the background, allowing gas plumes to be visualized even when no ambient light is present. If a camera includes a visible-light channel, it may require external illumination for visual context, but gas detection itself does not depend on lighting conditions.
In most cases, no. Standard thermal cameras are designed to measure infrared radiation emitted by solid surfaces and are not optimized to detect gases. Most gases are transparent to the broadband infrared spectrum used by conventional thermal cameras and do not produce a stable thermal signature. OGI cameras use narrow band-pass spectral filters tuned to specific gas absorption wavelengths, allowing gas plumes to be visualized as infrared contrast against the background.
