Automatic analyzers for rainfall and Automatic water sampling apparatus areusually used as monitoring systems for acid rain. Instead of these apparatus, a simple system which measurs hydrogen ion concentration and electric conductivityin rainfall was devised by using a personal computer. This system consists ofpH meter, electric conductivity meter, automatic level controller and personalcomputer. This paper showes that the system was able to usefully measure hydro-genion concentration in rainfall.
