PURPOSE:To measure without the addition of a harmful substance by collecting the distilled component with heating the sample sampled by the fixed quantity sampling mechanism of a sample inside a evaporating can and by measuring the conductivity of the collected liquid thereof with a conductivity measuring cell. CONSTITUTION:An evaporation can 1 having cleaning mechanism, a distillater and collection part 2 having a fixed quantity pouring mechanism of pure water and clenning mechanism and a fixed quantity sampling mechanism 13 of a sample are provided. Conductivity is measured by a conductivity measuring cell by introducing the collected liquid from which the distilled component was collected by heating within the evaporation can 1 the sample sampled by the fixed quantity sampling mechanism 13 of the sample. There is thus no necessity of adding a harmful component to towers and tanks sort of a plant and a concentration meter suitable for the measurement of concentration of volatile component of a free hydrochloric acid and nitric acid, etc. in the sample including salt is obtd. |
