ZR-7221 Portable Methane Non Methane Total Hydrocarbon Analyzer Introduction: The ZR-7221 Portable Methane Non Methane Total Hydrocarbon Analyzer is a portable device for detecting non methane total hydrocarbons. The total hydrocarbon and methane values are measured using a hydrogen flame ionization detector (FID) and specific catalytic oxidation techniques, and the difference between them is the non methane total hydrocarbon value. During the measurement process, in order to avoid interference caused by particles and condensed water in the sample gas entering the instrument, a sampling tube capable of tracing heat throughout the process and filtering particles is used for preprocessing to ensure accurate and reliable measurement data. Direct on-site counting eliminates the need to bring samples back to the laboratory for testing, enabling rapid and accurate on-site detection of "total hydrocarbons, methane, and non methane total hydrocarbons in ambient air and fixed pollution source exhaust gas.". It can be widely used in the field monitoring of non methane total hydrocarbons in organic chemical factories, surface coating industry, printing and dyeing industry, furniture manufacturing industry, automobile manufacturing industry, pharmaceutical industry, and other industries, as well as the monitoring of non methane total hydrocarbons in the atmospheric environment, and the evaluation and calibration of the accuracy of continuous smoke measurement instruments. characteristic: 1.
