The object of this paper is to be determined the calculation equation between the turbidity and the specific interfacial area of dispersion for emulsion systems. The emulsion was prepared by the Flow Jet Mixer. The droplet size distributions were concurrently measured by the turbidimetric method and the microscopic method. Distilled water and mixtures of n-C_7H_<16> and CCl_4 were used as continuous phase and the dispersed phase, respectively, in absence of emulsion agent. Hence, the following results were obtained. 1) The relationship between the turbidity, I, and the concentration of dispersed phase, C, were as following. log I=1.321 log C+β where β was the intercept. 2) As same as presented in term 1), the relation between the specific interfacial area, S, and the concentration of dispersed phase were represented by, S=-2046 log C+β' Consequently, where β' was the intercept. 3) Combining above two equations, the next calibration equation could be established for these emulsion systems. S=4505+log (I^<1590>/C^<2046>)
