SO2 analysis instrument
Description of SO2 analysis instrument :
SO2 analysis instrument by microprocessor as the core of intelligent signal converter and electrochemical sensors, import. Applicable to the metallurgical, coal, electric power, chemical industry such as carbon monoxide, hydrogen sulfide, hydrogen, nitrogen oxides, sulfur dioxide content such as automatic analysis. Instrument using controlled potential electrochemical principle, the sensor from the working electrode W, electrode, reference electrode R C, when the gas being measured by sensors, oxidation reaction in W electrode, the oxygen reduction reaction in C electrode, W electrode with C electrode between the size of the output signal is proportional to the measured gas concentration.
