•Dimensions : height 1.200mm x width 600mm x depth 600 mm (without PLC control module)
•Flow meter
Gas sampling and conditioning(accessible via the internal access front door)
•Pre-filtration by coalescing filter with peristaltic pump for continuous condensate removal
•Peltier gas cooler with digital temperature controller and peristaltic pump for continuous
condensate removal; gas dew point controlled @ +4°C ± 0,2°C
•H2S Scrubber on gas venting to atmosphere
* For outdoor installation, the cabinet needs to be fitted with the optional heater and to be
installed under a protective canopy for protection against rain, snow deposit and direct
sunshine radiations.
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.
9、Special designed gas conditioning system for biomass / syngas applications

To check the quality of the gas being produced prior to use in some industrial process. - To continuously monitor the efficiency of H2S scrubber installations
