Showcased Product
Our oxygen analyzers are engineered to deliver precise, real-time measurements across a wide range of applications—from trace-level monitoring in high-purity systems to combustion process control. Whether you’re working in air separation, pharmaceuticals, or flue gas optimization, these analyzers provide reliable and accurate readings for oxygen concentration in various forms and environments, ensuring safety, efficiency, and compliance.
Optical gas analyzers use advanced spectroscopic techniques such as NDIR, TDLAS, and DOAS to detect and quantify gas species with high selectivity, speed, and stability. These analyzers are ideal for challenging environments with complex gas mixtures, offering non-invasive and drift-free measurement. Suitable for emissions monitoring, process gas control, and environmental compliance, optical analyzers deliver long-term performance with minimal maintenance.
Moisture control is critical in industries where even trace amounts of water vapor can cause contamination or system failure. Our dewpoint and trace moisture analyzers provide fast, accurate detection of water content in gases—ranging from general dryness verification to ultra-low ppb levels in high-purity gas lines. These instruments help ensure product quality, prevent corrosion, and maintain compliance with industry standards.
Thermal conductivity analyzers offer a robust and straightforward method for measuring the concentration of gases within binary mixtures. By exploiting the thermal conductivity differences between gases, these analyzers provide continuous, drift-free measurements without requiring complex calibration. They’re widely used in hydrogen purity checks, binary gas separation monitoring, and inert gas applications where stable performance is essential.

Air Separation
Air separation plants require precise control and monitoring of gas composition during the production and purification of oxygen, nitrogen, and argon. Our analyzers ensure ultra-high purity, detect trace contaminants like moisture and hydrocarbons, and support reliable process control from raw air intake to final bottling.
Semiconductors & Specialty Gas
In semiconductor fabrication and specialty gas supply, ultra-trace detection is critical. Our instruments support ppb-level monitoring of oxygen, moisture, and hydrocarbon impurities in high-purity gases like nitrogen, argon, and helium, safeguarding product integrity and cleanroom standards.
Environmental Monitoring
Gas analysis plays a vital role in emissions tracking, ambient air quality monitoring, and regulatory compliance. Our solutions detect pollutants such as SO₂, NOx, CO, and volatile organic compounds (VOCs) across industrial and environmental applications, helping you meet evolving environmental standards.
Biopharmaceutical & Medical Gases
Pharmaceutical manufacturing and medical gas supply chains demand stringent quality assurance. We provide accurate analyzers for monitoring oxygen purity, controlling sterilization gas mixtures, and verifying compliance with pharmacopeial gas standards used in hospitals and life sciences.
Oil & Gas
From upstream drilling to downstream refining, gas analysis is key to process safety and efficiency. Our analyzers support flare gas composition, moisture and sulfur detection, fuel gas quality control, and leak monitoring, ensuring reliability in harsh environments.
Renewable & Bioenergy
Renewable gas sources such as biogas and syngas require accurate measurement of methane content, CO₂, and trace components like H₂S and NH₃. Our analyzers are used in process control, impurity removal efficiency monitoring, and performance validation in clean energy systems.
Power Generation & Utilities
Reliable moisture and gas composition measurement is critical in turbine operation, insulation gas monitoring, and boiler combustion control. Our instruments help optimize power plant efficiency, reduce corrosion risks, and maintain safe operating conditions.
Metallurgy
Gas monitoring in steelmaking, welding, heat treatment, and gas production is essential for product quality and safety. We offer analyzers for oxygen levels, furnace gas composition, and inert gas purity to help industrial manufacturers maintain consistent and efficient processes.
