Core Technologies
Six Core Technologies Mastered Independently
We have built a comprehensive underlying technology ecosystem in the industry, providing solid and reliable one-stop gas analysis solutions for complex applications.
Electrochemical Technology
ElectroSense —— Unlocking the Precise Language of the Gas World with the Key of Electrochemistry
In the invisible battlefield of industrial safety and environmental monitoring, every fluctuation in gas concentration is crucial to the balance of life and ecology. As a deep cultivator of electrochemical sensing technology, we take the name「ElectroSense」, transforming electrochemical principles into precise gas analysis solutions, and building an invisible protective network for global industrial safety, environmental monitoring and process control.

As a deep cultivator of electrochemical sensing technology, we take the name「ElectroSense」, transforming electrochemical principles into precise gas analysis solutions, and building an invisible protective network for global industrial safety, environmental monitoring and process control.
Optical Technology
Taking Light as a Ruler to Measure the Molecular Fingerprints of the Gas World, Making Every Beam of Light a Ruler of Safety. Over the years, we have deeply cultivated the field of gas analysis, and through numerous project practices and technological research processes, we have gained profound insights: traditional gas analysis technologies are gradually becoming inadequate, with frequent pain points emerging. As an industry pioneer, we have always upheld the core philosophy of "Precision, Stability, Intelligence" and turned our exploratory gaze to optical technologies. After unremitting efforts and continuous breakthroughs, we have found the key to solving industry pain points — safeguarding lifelines and the green sustainability of the ecological environment at the speed of light, and defining new standards for industrial safety with molecular-level precision.
Separation Technology
Chromatography Technology Innovation: Breaking the Boundaries of Efficiency and Precision in Analysis and Detection. Gas Chromatograph: A silent efficiency revolution is underway in global laboratory and industrial testing fields — chromatography analysis technology acts as the "invisible guardian" of quality control. With chromatography technology at our core, we are charging towards a future of higher efficiency, greater stability, more diversity, and higher precision, addressing the constraint of insufficient equipment adaptability that limits cross-border applications from laboratories to production lines, and from environmental monitoring to biomedicine. From efficiency to precision, from stability to diversity — we do more than solve pain points; we are redefining the possibilities of chromatography technology.
Microelectronics Technology
Every nanoscale breakthrough in microelectronic sensing technology is redefining the way humans converse with machines, and nature with cities. It is not only a "microscope" for industrial perception, but also a "catalyst" for the evolution of civilization — carrying greater missions in smaller volumes and driving a more sustainable future with more precise perception. We are witnessing the quiet arrival of a new era of "perceiving all things and intelligently connecting the globe".
Fluid Technology
When industrial processes march toward the goal of "zero error", mass flow meters are no longer isolated measuring components, but system solutions integrating materials science, fluid mechanics and digital technology. We continuously break through the boundaries of measurement accuracy and reliability, providing full-dimensional flow measurement solutions from micro-flow to high-pressure flow, and from single measurement to intelligent management and control for heavy industries such as chemical industry, energy and environmental protection, helping customers establish a decisive advantage in the dual tracks of quality competition and safety management.
Sample Pretreatment Technology
The Invisible Line of Defense for Precise Measurement in Industrial Processes: How Pretreatment Systems Reconstruct Analytical Reliability. When industrial measurement upgrades from the standard of pursuing "availability" to the realm of "reliability", pretreatment systems are quietly emerging as a key link. In the complex scenarios of heavy industries such as chemical engineering, energy, and environmental protection, the accuracy of process analysis is highly dependent on the quality of sample processing. We deeply recognize the importance of sample processing for analytical work, therefore, we focus on in-depth research on sample processing technologies, strive to break through traditional limitations, and tailor diverse sample processing solutions for different industrial scenarios.

Value of cooperation
Industry Opportunities
Global demand for gas detection continues to grow, with China's manufacturing advantages becoming increasingly prominent. This dual opportunity presents significant value for collaboration.
Global Market Demand Continues to Expand
The global gas detection equipment market is experiencing rapid growth, with a compound annual growth rate (CAGR) of 12%. Demand in Southeast Asia's environmental monitoring sector is growing at over 40%, while Europe's petrochemical industry is seeing an 18% annual increase in procurement of high-precision detection equipment. The Middle East's industrial safety equipment replacement cycle has also shortened to 3-5 years.
Simultaneously, essential market applications are comprehensively expanding. Dependence on specialized equipment continues to rise across multiple sectors—including industrial safety compliance, environmental pollutant monitoring, petrochemical process control, and high-purity gas detection in electronics—with stable procurement demand.
Furthermore, significant regional supply gaps exist. Emerging markets like Southeast Asia and the Middle East lack suppliers offering both “international certification and localized services,” while mature markets in Europe and North America exhibit strong demand for cost-effective specialized equipment. These market vacuums require urgent attention.
