Abstract: The test method of SO_2 automatic monitor based on ultraviolet fluorescence method is studied, for the first time. And the normalized method of the key qualifications is introduced. The experimental explanation is obtained by testing XHS2000 type SO_2 automatic monitor instrument. The method provides the theory basis for formulating the national metrology verification regulation of the gas online continuous monitoring system in our country, revising and improving the national environmental protection trade standards in the online detection, recheck, and calibration of field use.
