Acid rain is one of the serious problems for the global environment. It causes harms to the earth such as the lake acidification, melting of metallic constructions and so on. For mitigating these harms, we need to understand the generation mechanism of acid rain. For realizing it, we have newly developed a photoelectric optical fiber probe to measure pH, velocity and diameter of acid rain simultaneously. This probe has two functions of measuring the concentration of droplet by an electric sensor and measuring the velocity and diameter of droplet by an optical sensor. In this research, we examined modeled droplets including CO_2 gas. We describe the reliability of this probe for the droplet measurement of acid rain.
