The advantages and positive effects of the present invention are：
It 1, can be according to scene before being sampled at the scene by the present invention in that with the combined gas sampling probe of Portable heating
Flue depth selection different length probe tube carry out Rapid Combination, quick heating can be reached, bringing-up section is evenly distributed, and is adopting
The sample stage realizes the heating requirements of multitube, solves SO in flue gas2、NO2Problem soluble easily in water, energy under low temperature or room temperature
Temperature automatically controlled according to the requirement of temperature, outlet end fast pneumatic connector can be directly connected to heat tracing pipe and enter analyzer, ensure that cigarette
The continuous whole heating of gas special composition.
2, the present invention can also use the pressure measurement of compound tube group progress multiple spot other than smoke sampling, to prevent from being put into
It leaks out at the gaging hole of probe tube group and integrally has a down dip with probe tube group, increase an interface board with gasket, interface board inside
There is the limitation arc-like sheet of fixing pipe group with outside.The probe tube group reduces single probe tube and special messenger is needed to stare to keep and frequently change a little
Problem improves the working efficiency during measuring, and reduces sampling waiting time.
