Infrared CO/CO2 2-in-1 analyzer

Our company has launched an instrument that utilizes the principle of infrared spectroscopy absorption to measure low concentrations of carbon monoxide and carbon dioxide. Complies with the national standards of GB/T18204.2-2014 "Methods for hygiene inspection in public places - Part 2: Chemical pollutants", GBZ/T300.37-2017 "Determination of toxic substances in workplace air - Part 37: Carbon monoxide and carbon dioxide", and GB/T9801-1988 "Determination of carbon monoxide in air quality - Non dispersive infrared method".

This instrument complies with the national metrological verification regulations of JJG635-2011 "Infrared Gas Analyzer for Carbon Monoxide and Carbon Dioxide", and its main technical indicators meet the technical requirements of national secondary instruments. It can obtain a verification certificate from the Chinese Academy of Metrology (verification conclusion: qualified, this instrument meets the secondary technical requirements).
