7 Why should be GASBOARD 3000? 3. Why flue gas analyzer from Cubic can measure up to 5 components simultaneously? We adopts advanced microflow infrared gas sensors, four microflow gas sensors of SO2, NO,CO2,CO, together with an imported ECD(O2) of long working life are built inside in one single analyzer. 4. How to solve the inference from water vapor to SO2 and NOx? The traditional double-beam infrared gas sensor technology due to the impact of filter bandwidth, SO2, NOx and water vapor IR absorption peaks overlap, cross-infection is very serious. Experimental results show: 4 in the flue gas water vapor saturation SO2, NOx measurement results of up to ppm. Infrared gas sensors using micro-flow, while the water allocation of special compensation mechanism, to a large extent resolved gaseous water on SO2, NOx interference problems, after testing and validation, saturated air at room temperature for SO2, NOx maximum of only 5-8ppm 5. How to eliminate the environment s influence on flue gas analyzer? Ambient temperature change is inevitable, so in order to ensure the stability of infrared gas analyzer, the temperature correction method commonly used to address the changes in temperature brought on the application of instruments to measure results, the method applies only to air flow over Small, relatively constant temperature environment. Overall temperature sensor and the use of a combination of temperature correction method can solve the problem of environmental temperature
