As is well known to us, carbon dioxide leaks are invisible and intangible, and have long constituted a hidden blind spot in the realms of industrial safety, carbon accounting, and environmental management. Traditional detection methods require personnel to approach the leak source to perform point-by-point contact inspections—a process that is both inefficient and fraught with safety risks. Is there a technology that could make CO₂ leaks "visible," much like smoke? ULIRVISION provides the answer: the G430 CO₂ Optical Gas Imaging Camera—equipping CO₂ leak detection with a pair of "visualizing eyes."
Every gas molecule possesses a unique "spectral fingerprint"—specifically, infrared absorption peaks at distinct wavelengths. Take CO₂, for instance: it exhibits strong absorption of mid-infrared radiation in the 4.2-4.4 μm band. OGI (Optical Gas Imaging) devices are equipped with specialized narrowband filters that allow only infrared light within this specific band to pass through, while blocking radiation from all other wavelengths. Consequently, these devices transform gas leaks—which are otherwise invisible to the naked eye—into real-time, visible "smoke" or "clouds," leaving the source of the leak nowhere to hide and effectively acting as a "master detective" for gas visualization.
As the ULIRVISION G430 scans a target area, background objects—such as pipes, equipment, and the ground—continuously emit infrared radiation. If this radiation falls within the 4.2–4.4 μm spectral band as it passes through a cloud of leaking CO₂, it is absorbed by the CO₂ molecules, resulting in a significant attenuation of the radiation intensity reaching the detector. On the G430's screen, these areas of "missing" radiation appear as wispy black or colored plumes, rendering the location, shape, and dynamic diffusion process of the leak clearly visible at a glance.
The G430 is a cooled thermal gas imaging camera custom-engineered by ULIRVISION Technology specifically for carbon dioxide leak detection. Featuring an integrated design that combines a high-sensitivity detector, proprietary spectral filtering, intelligent image enhancement, and infrared thermometry, it is ideally suited for deployment in demanding field environments.
1. Cooled, High-Sensitivity Detector
The G430 is equipped with a cooled, high-sensitivity detector that is precisely matched to the characteristic CO₂ absorption band of 4.2–4.4 μm. By accurately covering this specific spectral range—which is exclusively locked to CO₂—it effectively eliminates interference from other gaseous components. With a CO₂ detection sensitivity of ≤3.24 g/hr, the device can precisely identify minute, industrial-grade carbon dioxide leak sources, ensuring that even the smallest target points are never missed.
2. Sharp Imaging, Intuitive Display
Supports optional standard and wide-angle lenses, featuring a versatile triple-mode focus system—electric, automatic, and manual—with a minimum imaging distance of 0.5m, making it ideal for tasks ranging from detailed close-range inspections to broad-area long-range scanning. The 5.0-inch, 1280x720 HD rotatable touchscreen remains clearly visible even in bright outdoor lighting conditions; furthermore, a built-in 5-megapixel visible-light camera enables fused imaging—combining the infrared gas view with the real-world visible-light scene—for more precise leak localization.
3. Multi-functional: Combining Gas Leak Detection with Infrared Thermography
The G430 is not merely a single-purpose leak detection device; it also features professional-grade infrared thermography capabilities. Its temperature measurement range spans from -40°C to +500°C, with an accuracy of ±1°C within the 0°C to 100°C range. Users can simultaneously perform precise surface temperature measurements while conducting leak detection, thereby aiding in the assessment of equipment operational status and the identification of potential overheating hazards. This dual functionality—combining CO₂ gas leak imaging with infrared thermography—enables the simultaneous detection of both gas leaks and thermal anomalies on equipment surfaces.
4. Lightweight Design for All-Weather Operation
The G430 features a compact and lightweight design, weighing in at just 2.8 kg. Its portable form factor allows for easy, single-handed operation in the field. The device supports an operating temperature range of -20°C to +50°C and boasts an IP54 protection rating, making it well-suited for use in a wide variety of industrial environments.
The range of industries requiring the detection of carbon dioxide (CO₂) gas leaks is extensive, primarily because such detection is critical to personnel safety, product quality, and environmental protection. At elevated concentrations, CO₂ displaces oxygen, thereby posing a risk of asphyxiation to personnel. Furthermore, in numerous manufacturing processes, controlling CO₂ leaks directly impacts both product quality and production efficiency. With its high efficiency, precision, and non-contact capabilities, the ULIRVISION G430 is ideally suited for identifying potential hazards across the entire carbon lifecycle—encompassing production, storage, transportation, and emissions.
CCUS: Carbon Sequestration and Pipeline Transport
In Carbon Capture, Utilization, and Sequestration (CCUS) projects, CO₂ is captured from industrial emission sources and subsequently transported via pipelines to sequestration sites. A leak occurring at any stage of this process would undermine the effectiveness of carbon reduction efforts. The G430 enables long-range leak inspections of CO₂ transmission pipelines, storage tanks, valves, and compressor stations; it captures high-pressure CO₂ leak plumes in real time, thereby preventing storage and transport losses, environmental fugitive emissions, and high-pressure safety hazards. This provides robust support for the safe operation of CCUS projects and the assessment of their carbon reduction efficacy.
Power Industry
In the operation and maintenance of hydrogen-cooled generators, CO₂ is frequently employed as a tracer gas to detect leaks within the hydrogen cooling system. The G430 enables rapid scanning of critical components—such as the generator casing and sealing systems—to precisely pinpoint leak locations, thereby reducing maintenance time and minimizing losses associated with downtime.
Oil & Gas Industry
In Enhanced Oil Recovery (EOR) projects, CO₂ is injected into oil reservoirs to boost crude oil production. Leaks of CO₂ from injection pipelines and wellheads not only result in resource waste but also pose significant safety risks. The G430 offers an efficient solution for leak detection in oil and gas field environments.
Environmental Regulation & Carbon Compliance Verification
Supporting environmental enforcement, corporate self-audits of carbon emissions, and the tracing of fugitive emissions, the device provides visual evidence of leak points. It meets the requirements of environmental protection agencies for carbon emission control, as well as the joint monitoring of VOCs and greenhouse gases.
Food & Beverage Industry
In processes such as beer brewing and carbonated beverage production, fermentation tanks and carbonation operations generate substantial amounts of CO₂. This gas tends to accumulate in relatively confined spaces—such as cellars and storage tanks—posing a significant asphyxiation risk to personnel. The G430 empowers safety managers to rapidly identify potential leak points, thereby ensuring the safety of the operational environment.
Scientific Research & Laboratories
Scientific institutions conducting CO₂-related reaction experiments or cell culture studies require precise control over gas concentrations and vigilant monitoring for leaks. The G430 provides laboratories with a visual method for leak detection, safeguarding the integrity and safety of experimental procedures.
Against the backdrop of increasingly stringent global regulations on greenhouse gas emissions and the full-scale operation of domestic carbon markets, the ULIRVISION G430 offers far more than just a detection instrument; it delivers a comprehensive, end-to-end visual management solution for industrial CO₂. It renders invisible leaks visible, brings minute, hidden hazards to light, and streamlines the efficiency of facility-wide inspections.
Invisible CO₂ fugitive emissions act as an unseen shackle on the path toward achieving industrial "Dual Carbon" goals;
Clear, visible infrared thermal imaging serves as the robust foundation for effective carbon emission management.
