应用
The analyzer can provide a variety of online running parameters and controlled states.H2S The gas is decomposed into SO2 by oxidation at high temperature in the air. The measurement of SO2 measures the concentration of SO2 by UV fluorescence, which is converted to the concentration of H2S.
-Optical switch periodic switch and optical flux detector automatic detection and compensation to improve the system stability.
-The "automatic zero point" cycle can continuously provide the real zero point parameters to ensure the stability of the instrument.
-An adaptive digital signal filter is used to set the sampling frequency.
