Cubic Instruments Profile Cubic Instruments (Wuhan) Ltd. (hereinafter referred to as "Cubic Instruments") is a wholly-owned subsidiary of Cubic Sensor and Instrument Co., Ltd.(stock code 688665.SH). Established in 2010, Cubic Instruments 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 advantages of Cubic core gas sensing technology platform, Cubic Instruments has developed a series of gas analyzers that utilize advanced technical principles such as non-dispersive infrared (NDIR) technology, ultraviolet differential absorption spectroscopy (UV-DOAS) technology, laser Raman (LRD) technology, ultrasonic technology, thermal conductivity (TCD) technology, and light scattering detection (LSD) technology. Cubic Instruments gas analyzers are widely used in environmental monitoring, metallurgy, coal chemical, biomass energy, and other industries, playing an important role in energy conservation and emission reduction. Cubic Instruments independently developed and produced portable infrared biogas analyzers, micro-flow infrared flue gas analyzers, and infrared gas analyzers that had successively obtained the national key new product certificate. 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. In 2019, the Ministry of Industry and Information Technology awarded Cubic Instruments "Research and Industrialization of Micro-flow Infrared Flue Gas Sensors" for the "key product and process" one-stop application program demonstration project. Cubic Instruments was also recognized as the "one-stop" application program demonstration enterprise for its contribution to the project. With decade-long dedications in technical innovations, strict quality control, and global business strategies, Cubic Instruments products have been exported to many countries and regions. Besides, Cubic Instruments is moving towards a higher target to be the international brand in the field of high-end and value-added applications of gas analysis instruments.

CUBIC Portable Particle Counter is designed to measure the particle number of fine particles in automotive exhaust gas. Based on DC (Diffusion Charge) principle, the portable particle counter determines the number of particles by measuring the charge carried on particles in sample gas. The exhaust gas can be directly measured, no need for filtration and dilution, ensuring long-term clean operation and reducing the maintenance costs effectively. The portable particle counter is designed with features of high sensitivity, high accuracy, fast response, excellent stability, etc. Its high-definition...
