AIR MONITORING Cutting-edge gas sampling solution


AGT-PSG GmbH presents its latest innovations in heated sample lines and gas analysis technology, designed for precise and reliable measurements even in the harshest industrial environments.


In 2025, AGT-PSG celebrates 50 years of innovation in gas analysis. Founded in 1975, the company has evolved into a global technology leader. A recent milestone includes the opening of its new, state-of-the-art headquarters in Hochheim am Main, Germany.


Research shows that up to 80% of gas analysis errors originate in the probe sampling system. AGT-PSG has tackled this challenge with integrated solutions that streamline system performance, reduce failure points, and increase operational efficiency.


At the heart of this approach is the PSG Process Probe, which operates at temperatures between 150°C and 180°C to prevent condensation and ensure accuracy. Fully compliant with ATEX standards, the probe features a built-in temperature limiter for safety


and an integrated shut-off valve to prevent gas leakage. With the largest active filter surface on the market, the probe offers extended service life and minimal maintenance. Optional back-purging capabilities further reduce manual intervention and downtime.


Following extraction, it is crucial to transport the gas sample under stable thermal conditions to preserve its composition. The PSG Plus Extruded ATEX 180 heated sample lines maintain internal temperatures up to 200°C, effectively preventing acid dew point condensation. Their cut-to-length design allows for flexible installation, while improved insulation technology lowers energy consumption by up to 25%—enhancing both sustainability and cost efficiency.


In the final stage before analysis, proper gas conditioning is essential. The PSG BCR03 ATEX Process Cooler supports safe and flexible multi-path configurations and ensures compliance with ATEX/IECEx regulations. For gas drying, AGT-PSG leverages


advanced Nafion dryer technology, developed in collaboration with PermaPure, which enables selective, non-electrical drying while preserving gas integrity and ensuring intrinsic safety.


With a comprehensive portfolio of safety-compliant, energy-efficient, and performance-driven technologies, AGT-PSG continues to lead in emissions monitoring. By optimising gas sampling, transport, and conditioning processes, the company delivers higher measurement reliability with lower maintenance requirements and energy usage.

Continuous air monitoring technology provides a solution to the health and environmental impact of sargassum


The ongoing influx of sargassum on Caribbean coastlines, especially along Mexico’s Quintana Roo region, has worsened a complex environmental problem. As the seaweed decays, it releases toxic gases like hydrogen sulphide (H₂S) and ammonia (NH₃), which threaten the health of local communities and tourists and also harm marine ecosystems. To address these concerns, a researcher from the National Polytechnic Institute, working with the Caribbean Air Quality Monitoring Network, launched a project to monitor gaseous emissions from sargassum decay.


Kunak’s AIR Lite


To provide accurate and real-time data on toxic gas levels, the research team collaborated with Repmex, Kunak’s distributor in Mexico, to deploy a network of Kunak air quality monitoring systems. Two Kunak AIR Lite units and one AIR Pro unit were strategically placed near the sargassum accumulation areas. These systems were equipped with sensors specifically designed to detect NH₃ and H₂S, and they were supplemented by a portable methane (CH₄) detector for personal safety, which included audio and visual alarms for operational safety during beach cleanup activities.


The monitoring stations, powered by solar panels to ensure continuous operation in remote coastal zones, also integrated mechanical anemometers to measure wind speed and direction—critical for modeling gas dispersion. All environmental data is transmitted wirelessly to the Kunak Cloud platform, enabling continuous remote analysis and system oversight without requiring on-site presence.


Initial findings from the deployment revealed clear connections between large sargassum landings and increased levels of H₂S and NH₃, confirming concerns about exposure risks for humans and wildlife. The dataset has allowed researchers to identify when and where exposure peaks occur, assess health risks, and support calls for expanded monitoring systems. These insights are already helping guide public health efforts, cleanup strategies, and early warning systems.


This initiative emphasises the technical feasibility and scientific importance of autonomous air quality monitoring systems in coastal areas, providing a scalable model for addressing the environmental impacts of sargassum in the Caribbean and beyond.

Oxygen measurement solution for combustion and incineration gases


Setnag is showcasing its latest innovation in gas analysis with the MicroPoas®


requires no reference gas. system, designed for precise measurement of oxygen in


combustion and incineration gases. Unlike traditional solutions, the MicroPoas®


Offering robust performance in extreme environments, Setnag analysers can handle continuous gas temperatures of up to 1300°C, depending on the version. ATK analysers feature a design free from sensitive parts or hot spots inside the duct, allowing gases to circulate naturally for accurate analysis. Its detachable probe tubes enable simple replacement and cost-effective maintenance, while routine cleaning is easily achieved with compressed air or rapid dismantling.


The system operates by directing gases through co-circular tubes to the MicroPoas®


sensor, where temperature and voltage signals are collected to determine oxygen concentration. Typical applications


include combustion control in power generation and district heating, industrial and domestic waste incineration, VOC incineration, and various process control scenarios.


Setnag hopes this innovative solution can improve efficiency and compliance in high-temperature gas measurement applications. More information online: ilmt.co/PL/ew9X
