Enterprise Introduction


Hubei Cubic-Ruiyi Instrument Co., Ltd. (hereinafter referred to as ”Cubic-Ruiyi” ) is a wholly-owned subsidiary of Cubic Sensor and Instrument Co., Ltd.(stock code 688665). Established in 2010, Cubic-Ruiyi is a high-tech enterprise specializing in providing gas composition and gas flow measurement solutions in the fields of environmental monitoring, process gas monitoring, and smart metering.

Based on the advantaged of Cubic Sensor core gas sensing technology platform, Cubic-Ruiyi developed a series of gas analyzers with advanced technical principles, such as non-dispersive infrared (NDIR) technology, ultraviolet differential absorption spectroscopy (UV-DOAS) technology, laser Raman (LRD)technology, ultrasonic (Ultrasonic) technology, thermal conductivity (TCD) technology, light scattering detection (LSD) technology and etc. Widely used in environmental monitoring, metallurgy, coal chemical, biomass energy and other industries and play an important role in energy saving and emission reduction.Cubic-Ruiyi independently developed and produced portable infrared biogas analyzer, micro-flow infrared flue gas analyzer, and infrared gas analyzer have successively obtained the national key new product certificate, And the infrared gas analyzer has won the honor of the outstanding product award of the Chinese Instrument and Control Society, and its core technology Won the Hubei Province Invention Patent Gold Award. The “Research and Industrialization of Micro-flow Infrared Flue Gas Sensors” was awarded by the Ministry of Industry and Information Technology for the key “products and processes” one-stop application program demonstration project of the Ministry of Industry and Information Technology in 2019, and Cubic-Ruiyi was awarded the “one-stop” application program demonstration enterprise.

With decade-long dedications in technical innovations, strict quality control and global business strategies, Cubic-Ruiyi products have been exported to many countries and regions, besides, Cubic-Ruiyi is moving towards a higher target to be the international brand in the field of high-end value-added applications of gas analysis instruments.
