In recent years, the import cost of high-end instruments and equipment has sharply increased due to the dual impact of geopolitics and supply chain disruptions, coupled with the bundling and certification barriers of European and American technology. Domestic enterprises have fallen into the dilemma of "unable to afford, repair, or replace". The country has elevated the research and development of scientific instruments to a strategic level through major scientific research projects and five-year plans, giving domestic instruments an advantageous position from the perspectives of research and development, production, and government procurement.
In this situation, significant progress has been made in the localization of heat flow meters, and domestically produced heat flow meter equipment has reached the international advanced level in core indicators such as heating and cooling rate, temperature range, and accuracy. For example, ZONGLEN's heat flow meter has an ultra fast heating and cooling rate, which can complete temperature changes from -55 ℃ to+125 ℃ in about 10 seconds. It can simulate a temperature range of -90 ℃ to+225 ℃ with small temperature deviation, meeting the detection needs of optical modules in temperature changing environments. In the field of optical communication, ZONGLEN has occupied the majority of the domestic heat flow meter market, with over 87% of optical module workshops equipped with its equipment. In the overall market of environmental testing equipment, domestic brands will have a market share of 80% in 2024, with a significant dominant position.
In addition, domestic heat flow meters have demonstrated unique advantages in intelligence, automation, and system integration, which can significantly improve testing efficiency and data accuracy. With the rapid development of high-end fields such as 5G, data centers, and intelligent driving, the demand for thermal flow meters in optical modules continues to upgrade. Domestic thermal flow meters, with their excellent performance and stable service capabilities, have gradually broken foreign monopolies and become the mainstream choice in the industry.
Domestic heat flow meters not only have technological advantages, but also have more obvious advantages in cost and service. The price of domestically produced heat flow meter equipment has been significantly reduced compared to imported products, and the localized supply of spare parts and timely support from after-sales personnel have significantly reduced maintenance costs. Domestic heat flow meters focus on the timeliness and quality of after-sales service, providing customers with quick response technical support and equipment maintenance services. For example, ZONGLEN has offices in Beijing, Shanghai, Suzhou, Kunshan, Shenzhen, Xi'an, Wuhan, and Chongqing to achieve fast delivery and local technical response.
Domestic heat flow meters still face some challenges, with high-precision detectors still relying on imports. Users have concerns about the stability and repeatability of domestic heat flow meters, and the verification cycle can take up to 3-5 years. Domestic heat flow meters need to continuously strengthen research and development investment, enhance independent innovation capabilities, and launch diversified product solutions for different application scenarios. This has made domestic heat flow meters widely popular and highly recognized in universities, research institutions, and many industrial fields.
Compared with foreign manufacturers, domestic heat flow meters are easier to match the actual needs of domestic users and have stronger customized development capabilities. Through continuous technological iteration and service optimization, domestic heat flow meters are accelerating the standardization and localization process in China's thermal management testing field, helping to promote high-quality development of the industry.
