PRI-5251f Plus CO CO₂ CH₄ N₂O H₂O Greenhouse Gas Measurement System, a new solution for high- precision, multi-component flying greenhouse gas measurements. The system consists of a high-precision, multi- component greenhouse gas analyzer module, a miniature meteorological station, and the ELF-600 hexacopter unmanned aerial vehicle (UAV) system, and is capable of simultaneous on-line measurements of the three main greenhouse gases (CO₂ N₂O CH₄), associated gases (CO) and water vapor (H₂O), as well as 3D ultrasound, air temperature and humidity, atmospheric pressure and other parameters. The PRI-5251f Plus CO CO₂ CH₄ N₂O H₂O analyzer at the core of the system is based on an innovative miniature laser sensor engine, which provides higher precision, accuracy, and a wide range of gas concentration data through the extremely strong spectral absorption in the mid-infrared wavelength band, with ppb-level sensitivity; and is optimized for the best fit for the micro- drone in terms of the comprehensive and optimized design of the size, weight, and low-power consumption and overall performance. The overall performance is optimized in terms of size, weight, and low power consumption.        PRI-ECO has been deeply engaged in the field of greenhouse gas scientific research and monitoring for 16 years, and has undertaken and participated in major instrument research and development projects awarded by the Ministry of Science and Technology (twice), Chinese Academy of Sciences and Beijing Municipal Science and Technology Commission. PRI-ECO has excellent instrument research and development, design and production capabilities, can provide a variety of high, medium and low precision greenhouse gas analyzers and spectral isotope analyzers. In the practice of providing customers with technical support and system solutions has accumulated rich experience, for the effectiveness assessment of domestic "double carbon" action, Priyke   has

the strength to provide "scientific, accurate, complete and systematic" carbon measurement solutions.
