DEVELOPMENT AND EVALUATION OF AN ACID PRECIPITATION MONITOR FOR FRACTIONAL EVENT SAMPLING WITH CAPABILITY FOR REAL-TIME PH AND CONDUCTIVITY MEASUREMENT.

Description:
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. -80 microprocessor controls all operations of the monitor including sample collection, sample analysis, quality control analysis, and data recording. uality control analysis consists of analysis upon demand of a low-ionicstrength solution. he monitor was evaluated in the field and about 40 rain events were monitored. xcellent stability of the pH electrode was found under field conditions.
