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、RS-232 digital output and 4-20mA analog output interface.
7、Auto zeroing function.
