GasFIR SF6
OGI Camera
Portable optical gas imaging camera for SF₆ leak detection and visualization
Detect SF₆ Leaks from a Safe Distance
Designed for real-time sulfur hexafluoride (SF₆) leak detection, the Pergam GasFIR SF6 uses optical gas imaging (OGI) to make escaping gas visible. Its infrared imaging system allows operators to inspect suspected leak points from a distance, without direct contact with the equipment. Besides SF₆, the camera can detect other gases, including ethylene, methyl ethyl ketone, Freon-12, acetic acid, chlorine dioxide, and ammonia. The GasFIR SF6 also measures surface temperatures and records images and video. It is particularly useful for inspecting electrical substations and facilities that use SF₆-filled switchgear or circuit breakers.
What Is SF₆ and Why Does It Matter?
Sulfur hexafluoride (SF₆) is a colorless, odorless gas used in high-voltage equipment for electrical insulation and arc quenching. Its excellent insulating properties make it ideal for gas-insulated switchgear and circuit breakers, where space and reliability are critical. However, SF₆ is also an extremely potent greenhouse gas. Leaks can release SF₆ into the atmosphere, making regular leak detection essential for reducing emissions and maintaining equipment reliability.

How GasFIR SF6 works
GasFIR SF6 makes invisible sulfur hexafluoride leaks visible by visualizing infrared contrast created as SF6 absorbs background IR radiation. Using special filters, the camera shows SF6 emissions as clouds on the screen in real time, allowing for safe and efficient leak detection without physical contact.

FAQ
Honest answers to important questions
An optical gas imaging (OGI) camera uses infrared technology to visualize gas escaping from equipment in real time. Unlike conventional gas detectors, which measure gas concentration at a specific point, an OGI camera shows the gas plume, helping operators locate potential leaks from a distance without direct contact with the equipment.
No. OGI cameras are designed to visualize specific gases that absorb infrared radiation within the camera’s spectral range. Whether a gas can be detected depends on its infrared absorption characteristics and the camera’s specifications.
Designed primarily for SF₆ leak detection, the Pergam GasFIR SF6 can also visualize certain other gases, including ammonia, ethylene, acetic acid, chlorine dioxide and Freon-12.
The GasFIR SF6 uses infrared imaging to visualize escaping gas in real time. Its Gas Visualization Enhancement (GVE) mode improves the visibility of gas plumes against the background.
The camera is particularly relevant to electrical substations and facilities that use SF₆-filled switchgear or circuit breakers. It can also be used in industrial applications where other gases detectable by the camera are present.
Yes. Optical gas imaging allows operators to inspect suspected leak points without touching the equipment. The practical detection distance depends on factors such as the gas being detected, the size of the leak, weather conditions and background temperature.
No. The infrared camera must have a suitable line of sight to the escaping gas. If a wall, enclosure, or other obstruction blocks the view, the camera cannot directly visualize a leak behind it.
Yes. In addition to gas imaging, the camera measures surface temperatures from -40 °F to 932 °F.
Not in every application. OGI cameras provide a visual way to locate suspected leak sources, while conventional detectors can measure gas concentration at a sampling point or provide alarms. The methods serve different purposes and can complement each other.
