The PRI-5251 Plus CO CO2 CH4 N2O H2O analyzer meets the World Meteorological Organization (WMO) greenhouse gas (GHG) observation specifications. It is capable of simultaneous on-line measurement of the three main greenhouse gases (CO2 CH4 N2O) and associated gases (CO) and water vapor (H2O) with ppb-level accuracy, and it has a high data acquisition frequency (1Hz). The PRI-5251 plus is a fully pre-calibrated mid- infrared (MIR) laser spectroscopy gas analyzer that enhances analytical target specificity, resolution, accuracy, and stability through superb absorption of target gases in the mid-infrared (MIR) band. The smaller measurement chamber is conducive to higher turnover rate at lower gas flow rate, which ensures accurate pressure and temperature control, thus improving the stability and data accuracy of the instrument; the scientific and solid anti-vibration and anti-shock design ensures that the instrument can be used in a variety of special occasions, such as on-board the vehicle, aircraft, ship and other special occasions.
PRI-ECO has been deeply engaged in the field of GHG scientific research and monitoring for 16 years, and has undertaken and participated in major instrument R&D projects granted by the Ministry of Science and Technology, the Chinese Academy of Sciences, and the Beijing Municipal Science and Technology Commission, etc. PRI-ECO has excellent instrument R&D, design, and production capacity, and can provide a variety of high-, medium-, and low-precision GHG analyzers and isotope analyzers; and has accumulated a wealth of experience in providing technical support and system solutions for customers. We have accumulated rich experience in providing technical support and system solutions to our customers. In order to assess the effectiveness of the "Double Carbon" action in China, PREMIUM has the strength to provide "scientific, accurate, complete and systematic" carbon measurement solutions.
