PROBLEM TO BE SOLVED: To evaluate under a wide range of density stratification conditions conforming to a purpose. SOLUTION: This testing apparatus includes a water bath 1, a sodium sulfate aqueous solution 2 in the water bath 1 of one layer or forming a plurality of stratums depending on a concentration and adjusted to a predetermined specific gravity, a tracer aqueous solution of inorganic salt different from the sodium sulfate aqueous solution 2, a discharge pipe 3 discharging the tracer aqueous solution and chlorine ion electrodes 6-8 for measuring a concentration of inorganic salt ions. A state of diffusion of the tracer aqueous solution is measured by measuring the concentration of ions. |
