Sulfur dioxide gas measurement method and measuring device

摘要

PROBLEM TO BE SOLVED: To provide a method with which it is possible to continuously observe the state of presence of a sulfur dioxide gas, and a device therefor.SOLUTION: There is provided a method for measuring a SOgas characterized by including the steps of: determining a correlation between a ratio of PbOquantity to a total quantity of PbOquantity and PbSOquantity and electrical resistance; creating an SOevaluation test piece containing PbOon the basis of the determined correlation; installing the SOevaluation test piece in an environment of measurement object and measuring the electrical resistance of the SOevaluation test piece in the environment; and finding, from the measurement result of electrical resistance of the SOevaluation test piece in the environment, an SOabsorption quantity of the SOevaluation test piece in the environment on the basis of the correlation between the ratio of PbOquantity and the electrical resistance.SELECTED DRAWING: Figure 5
