摘要

An acid precipitation monitor has been developed that collects fractions of rain events, measures the pH and conductivity in real-time, and stores the remaining samples under refrigerated conditions. A Z-80 microprocessor controls all operations of the monitor including sample collection, sample analysis, quality control analysis, and data recording. Quality control analysis consists of analysis upon demand of a low-ionic-strength solution. The monitor was evaluated in the field and about 40 rain events were monitored. Excellent stability of the pH electrode was found under field conditions.
