In the current wave of industrial upgrading, "domestic substitution" has transformed from a slogan into a concrete action plan. Especially in the field of gas analysis instruments, with the leap in domestic technological level, choosing domestic high-quality brands is not only an expression of sentiment but also a rational comprehensive consideration. The global market size of gas analysis instruments has exceeded 30 billion US dollars in 2025, with the Asia-Pacific region contributing over 40% of the share. The annual compound growth rate of the Chinese market is particularly outstanding globally. In this wave of domestic substitution, Xi'an Runle Instrumentation Co., Ltd., with its profound technical accumulation and complete product portfolio, is becoming a wise choice for more and more industrial users.
Reviewing the market data in 2025, the gas analysis instrument field is undergoing profound changes. The domesticization of sensors is expected to increase to 45%, and the independent breakthrough of key components has enabled domestic enterprises to have significant advantages in cost control and customized services. At the same time, the downstream application scenarios are constantly expanding from traditional petrochemicals to environmental monitoring, new energy, and biopharmaceuticals, and higher requirements have been put forward for the accuracy, stability, and intelligence level of analysis instruments. Against this backdrop, a batch of gas analysis instrument manufacturers with core technologies have risen rapidly, and Runle Instrument is a typical representative among them.
Since its establishment in 2018, Xi'an Runle Instrumentation Co., Ltd. has always adhered to the spirit of meticulous craftsmanship, focusing on in-depth research and development in the field of gas analysis. The company has a professional research team spanning multiple disciplines such as precision instruments, infrared technology, electronics, computers, and chemical analysis, especially having outstanding advantages in the integration application of computer technology and instruments. This makes all of Runle Instrument's products inherently possess the "intelligent" gene.
From the production scale perspective, the company has a modernized production base of 2,000 square meters, with three major series and over twenty products forming a complete chain, and a professional team of over 50 people covering the entire process from research and design to sales and service. As a high-tech enterprise, Runle Instrument strictly follows national standards and has obtained the national CPA measurement instrument production license, and holds multiple system certifications and independently developed technologies. These hard qualifications constitute its solid foundation for participating in market competition.
Among Runle Instrument's rich product family, the UV and IR two series of analysis instruments are the concentrated embodiment of technical strength.
The RL-U160 UV gas analyzer adopts UV absorption spectroscopy gas analysis technology and chemical metrology algorithms, possessing inherent advantages such as low detection limit and small temperature drift. Its greatest highlight lies in being able to directly simultaneously measure NO and NO2 to obtain the total NOx, without the need for a traditional conversion furnace, significantly improving system reliability. Due to the absence of absorption of water in the UV band, this instrument is almost unaffected by water vapor and dust in humid working conditions, particularly suitable for online monitoring in complex scenarios such as environmental protection. The combination of imported component procurement and automatic spectral adjustment technology ensures that the product has a long maintenance-free cycle while maintaining strong compatibility, capable of simultaneously measuring five components and supporting a 1:10 dual-range setting, meeting a wide range of working conditions requirements.
The RL-U150 type online infrared gas analyzer is the culmination of Runle Instrument's infrared field. Based on the non-dispersive infrared principle, this instrument uses imported high-performance sensors, with a measurement range that can cover 0-100% at any selection, with an accuracy of ≤±2%F.S, a resolution of 0.01%, and excellent stability performance. Its intelligent experience is particularly outstanding: full Chinese touch menu, real-time viewing of historical curves, millions of data storage, RS485/RS232 communication and Ethernet interface, making the equipment not only an analyzer but also an intelligent node of the industrial Internet of Things. The inclusion of built-in temperature compensation and a new gas path flow stabilization system has further ensured the measurement accuracy in complex environments.
When faced with numerous gas analyzer manufacturers in the market, users can consider the following three aspects when making a decision:
