NDIR Portable Infrared Syngas Analyzer: Part No: INGA-11001 Description: The instrument can be used for measurement of the concentration of CO ,CO2 ,CH4 ,H2 and O2 in sample gases simultaneously and also calculated heating value(caloric value ) automatically. powered by Li- ion battery. Based on the NDIR and Thermal Conductivity Detector. Application: Coal or biomass gasification, coal chemical process, heating treatment, steel making process such as blast furnace, Converter, Coking, Direct Iron Ore Smelting Reduction Process. Features: --1. Adopt international advanced NDIR and TCD gas analysis technology. --2. Can measure the concentration of CO ,CO2 ,CH4 ,H2 ,O2 ,CnHm simultaneously. --3. Automatically calculated heating value，the unit can be switch on/off between Kcal/m³ and Mj/m³. --4. CnHm gas has no interference with CH4 measuring result. --5. H2 reading is compensated for the interference effects of the CO ,CO2 ,CH4 measured. --6. Built-in sampling pump. --7. Storage function. --8. RS-232 digital output interface.
