Gasboard—3100P portable infrared syngas analyzer can be used for measurement of the concentration of CO, CO2, CH4, CnHm, 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.

Coal or biomass gasification, coal chemical process, heating treatment, steel making process such as blast furnace, Converter, Coking, Direct Iron Ore Smelting Reduction Process.

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.
