In an industrial environment with accelerated innovation and iteration, Guoke Hanhai's 15-year focus on laser gas monitoring is sometimes misunderstood as "outdated technology or low market acceptance," leading to doubts about Hanhai's "technology development rhythm" and "technical route choices." In fact, since its establishment in 2010, we have deeply cultivated TDLAS technology and continue to be an "invisible champion" guarding China's industrial safety with iterative TDLAS core technology and solutions tailored to domestic industrial pain points. We are not a "fast company" chasing short-term trends, but an industry deep cultivator that befriends time and breaks through technological barriers with perseverance.

01 15 Years of Persistence: Courage and Perseverance to Transcend Cycles

When it comes to "not crossing borders for 15 years," some question "whether we can keep up with technological iteration," but overlook the essence of "slow is fast" in the industrial detection field. The "slowness" of industrial detection is precisely the "stability" of its value. Industrial gas monitoring has unique attributes: technology must undergo long-term verification under complex working conditions such as high temperature, high humidity, and high salt spray, and must adapt to the unique needs of domestic refining, oil and gas, ports and other industries. Every breakthrough cannot do without long-term scenario refinement and technological accumulation, and can never be achieved overnight through "concept hype."

Hanhai Optoelectronics' persistence is precisely in line with the core logic of industry development:

Refusing to follow the trend and cross borders: When tracks such as environmental monitoring and intelligent equipment were booming, Hanhai has always focused on TDLAS laser spectroscopy technology itself, advancing steadily from laboratory principle verification to industrial scenario implementation.

Conquering tough challenges: In the early days, the domestic optical instrument detection market was monopolized by European and American brands. The Hanhai team spent 5 years breaking through the core algorithm of "selective absorption of gas molecules," and another 3 years completing 12 qualification certifications such as explosion-proof and metrology, finally realizing 100% localization of equipment in 2018.

Transcending industry cycles: After multiple rounds of adjustments such as the upgrading of environmental protection policies and the transformation of the refining and chemical industry, Hanhai has grown its customer base from 3 to nearly 100 with stable technical output and scenario adaptation capabilities, including industry leaders such as Sinopec and CNOOC. 15 years is not a sign of "technological stagnation or backwardness," but a manifestation of "long-termism" in the industrial detection field, a deep understanding and continuous response to industrial needs, and the most valuable perseverance and courage in this "slow track" of industrial detection.

02 Core Technological Strength: Achieving Multiple Key Breakthroughs in TDLAS

Some claim that "Hanhai's technology is outdated," which actually reflects a lack of understanding of the development of domestic laser detection technology. In fact, Hanhai's TDLAS technology has achieved multiple key breakthroughs, fully meeting the core needs of domestic industrial safety and the dual carbon goals:

Precision and Responsiveness: Exceeding Industry Average

Achieves ppb-level trace detection, with an identification error of ≤±5% F.S for toxic and harmful gases such as hydrogen sulfide and ethylene, which is better than the domestic industry standard (±20% F.S), and can accurately capture tiny leaks of 0.1 L/min.

0.1-second ultra-fast response, 300 times faster than traditional point sensors, winning valuable time for emergency disposal in scenarios such as refining equipment leaks and oil and gas pipeline inspections. These indicators have reached the international advanced level and are more suitable for the actual combat needs of high-risk domestic industrial scenarios.

Scenario Adaptability: Understanding Chinese Industry Better Than European and American Brands

Targeting the characteristics of "old equipment and complex working conditions" of domestic refining and chemical enterprises, we have developed wide-temperature equipment (-40℃~+60℃) that adapts to the harsh cold in Northeast China and high temperatures in South China. The IP68 protection level can cope with high salt spray working conditions in coastal ports, while the failure rate of some European and American brand equipment in extreme environments is as high as 30%.

Covers 16 types of core gases in domestic industry (methane, ethylene, hydrogen sulfide, etc.) and can customize detection solutions according to enterprise needs. For example, the special monitoring equipment developed for the ethylene plant of Yanshan Petrochemical has improved detection efficiency by 50% compared with general-purpose European and American equipment.

Cost and Service: Cost-Effective Advantage Breaking "Import Dependence"

The price of core equipment is only 60% of that of European and American brands, but the service life is up to 10 years, and the annual maintenance cost is reduced by 50%, perfectly solving the pain point of domestic enterprises "wanting to use good equipment but having limited budgets."

7×24-hour localized service response, with on-site maintenance within 48 hours for equipment failures, while the after-sales cycle of European and American brands often exceeds 15 days. This dual advantage of "technology + service" is Hanhai's unique competitiveness after 15 years of deep cultivation in the domestic market.

03 Value Reconstruction: Hanhai's "Slowness" Is the "Speed" of the Future

In terms of "growth potential" and "investment value" concerned by the capital market, Hanhai's 15 years of deep cultivation have built an irreplicable competitive barrier. It is now ushering in deep resonance with market demand and showing considerable growth potential:

Market Space Driven by Policy Dividends

With the revision of the new version of "Code for Design of Detectors for Flammable and Toxic Gases in Petrochemical Industry" (GB/T50493-2019), the demand for updating laser monitoring equipment in domestic refining, oil and gas, ports and other fields will explode, and the market size is expected to exceed 10 billion yuan in the next 3 years.

Driven by the dual carbon goals, enterprises' demand for VOCs emission and greenhouse gas monitoring has surged. Hanhai has launched special equipment for carbon emission monitoring, which can accurately measure the concentration of carbon dioxide and methane, seizing the opportunity in the green transformation track.

Customer Stickiness and Industry Reputation

Serving nearly 100 industrial customers for 15 years, the system equipment has been operating safely for 10 years at Beijing Gas, 8 years at PetroChina Shanjing IV Pipeline, and 7 years at CNOOC Hengqin LNG Terminal.

Participated in the formulation of 5 industry standards such as "Technical Requirements for Laser Gas Detectors," becoming one of the "standard setters" in the domestic industrial safety monitoring field, and the brand influence continues to rise.

Team and Technology "Moat"

The core R&D team has an average of more than 10 years of industry experience, and the team has obtained 42 patents, among which the "TDLAS-based urban gas leak detection system" won the Science and Technology Achievement Award of the State Administration of Work Safety.

Established a full-chain capability from technology R&D, equipment production to scenario implementation, without relying on external technical authorization, and has significant advantages in supply chain stability and technological iteration speed.

04 Conclusion: Time Is the Best Touchstone

Innovation and practice in the industrial field often require the patience and perseverance to "sit on the cold bench." Hanhai's 15 years of persistence may not be "fashionable" and may have missed many short-term capital hotspots, but the laws of industrial development tell us:

Genuine technological breakthroughs require time to precipitate;

True industrial value requires long-term verification.

The persistence of the Hanhai team is not the stubbornness of "backwardness," but the original aspiration of respecting technology and being responsible to customers, as well as a profound insight and firm response to the long-term demand for domestic industrial safety upgrading and green development.

Time witnesses value, and persistence nurtures the future. Today, when policy dividends resonate with industrial demand, and with the advancement of domestic industrial safety upgrading and dual carbon goals, Hanhai's technological value is accelerating its release. It is not a follower that needs to "prove itself not backward," but a "preparer" that has built a solid barrier in 15 years and is waiting for the industry outlet. Only by seeing the technical strength and market potential behind this "long-termism" can we truly understand Hanhai's value.

Guoke Hanhai, 15 years of deep cultivation in laser monitoring, guarding industrial safety with perseverance, and empowering China's intelligent manufacturing with technology!
