As the "Regulations on Ecological Environment Monitoring" is officially released and set to take effect on January 1, 2026, greenhouse gas emission monitoring has been explicitly incorporated into the legal framework, rigidly strengthening enterprises' responsibility for self-monitoring. Meanwhile, the "Work Plan for Improving the Carbon Emission Statistics and Accounting System" proposes establishing a comprehensive annual and express carbon emission reporting system by 2025. Pilot carbon monitoring projects in six key industries including thermal power, iron and steel, and cement are advancing steadily, making accurate and compliant carbon data a core necessity for enterprises' carbon management.

Traditional accounting methods rely on activity level data and emission factors, struggling to capture real-time emission fluctuations. High-end monitoring solutions, on the other hand, are often costly, putting them out of reach for small and medium-sized enterprises. Backed by over a decade of experience in laser spectroscopy technology, Guoke Hanhai has launched a refined carbon management solution centered on TDLAS (Tunable Diode Laser Absorption Spectroscopy), resolving the industry contradiction between "precision monitoring" and "cost control".

As a technical benchmark in the laser gas detection field, Hanhai's solution boasts dual breakthroughs in "low cost + high precision". It adopts gas molecule "fingerprint" recognition technology, where lasers precisely match the characteristic absorption lines of greenhouse gases, completely avoiding cross-interference. With a detection sensitivity reaching ppb level, it achieves trace monitoring precision comparable to laboratory standards. Compared with traditional spectroscopy and chromatography-based solutions, TDLAS technology simplifies complex optical structures, reducing hardware costs while maintaining millisecond-level response speed and long-term stability, alleviating the burden on enterprises throughout the entire process from equipment procurement to operation and maintenance.

The solution covers full-scenario carbon monitoring needs. For enterprise pollution source emissions, fixed online monitoring equipment is deployed to capture real-time data of greenhouse gases such as methane and carbon dioxide, supporting seamless connection to central control platforms via RS485 communication. For park or regional monitoring, portable telemetry equipment is paired to enable non-contact rapid inspections. Through an "end-edge-cloud" collaborative architecture, it completes high-frequency data collection, edge computing, and encrypted transmission, meeting both government regulatory requirements and ensuring enterprise data security.

From oil and gas extraction to chemical parks, from the power industry to waste treatment, Hanhai's solution has served numerous customers across various sectors. With an IP54 protection rating and wide temperature adaptability ranging from -25℃ to +50℃, it can easily cope with harsh working conditions. Its user-friendly operation, convenient maintenance, and long service life further reduce enterprises' operational costs. Without high investment, enterprises can obtain continuous, reliable, and compliant carbon data, providing solid support for their participation in the carbon market, carbon footprint accounting, and the formulation of emission reduction strategies.

Guoke Hanhai breaks industry barriers through technological innovation, bringing lab-grade precision carbon monitoring to thousands of enterprises. In the future, it will continue to deepen TDLAS technology iteration, helping enterprises achieve compliant efficiency improvement and low-cost transformation in the "dual carbon" track, and jointly building a precise and efficient carbon management ecosystem.
