一、颗粒物等速采样原理：将采样管由采样孔放入烟道中，将采样嘴置于测点上，正对气流方向，按等速采样要求抽取一定量的含尘气体，根据滤膜捕集到的烟尘重量以及抽取的气体体积，计算颗粒物的排放浓度及排放量。
LB-70C型自动烟尘烟气采样器的微处理器测控系统根据各种传感器检测到的静压、动压、温度及含湿量等参数，计算出烟气流速、等速跟踪流量，测控系统将该流量与流量传感器检测到的流量相比较，计算出相应的控制信号，控制电路调整抽气泵的抽气能力，使实际采样流量与计算的采样标准流量相等；同时微处理器用检测到的流量计前温度和压力自动将实际采样体积换算为标况采样体积。
二、含湿量测量原理：LB-70C型自动烟尘烟气采样器的微处理器控制传感器测量、采集湿球、干球表面温度以及通过湿球表面的压力及排气静压，结合输入的大气压，同时根据湿球表面温度自动查出该温度下的饱和水蒸气压力--Pbv，根据公式计算出烟气含湿量。
三、含氧量测量原理：将采样管放入烟道中，抽取含有O2 的烟气，使之通过O2电化学传感器，检测出O2的瞬时浓度，同时根据检测到的O2浓度，换算出空气过剩系数α。
四、SO2、NO、NO2、CO、H2S、CO2瞬时浓度及排放量测量原理：将采样管放入烟道中，抽取含有SO2、NO、NO2、CO的烟气，进行除尘、脱水处理后再通过SO2、NO电化学传感器，分别发生如下反应：
SO2+2H2O —> SO42- + 4H++2e-
NO +2H2O —> NO3- + 4H++3e-
NO2+ H2O —> NO3- + 2H++2e-
CO +2H2O —> CO32- + 4H++2e-
传感器输出的电流的大小在一定条件下与SO2、NO、NO2、CO的浓度成正比，所以测量传感器输出的电流即可计算出SO2、NO、NO2、CO的瞬时浓度；同时仪器根据检测到的烟气排放量等参数计算出SO2、NO、NO2、CO的排放量。
