AUTOMATIC MEASUREMENT SYSTEM OF ACIDITY OF ACID RAIN

摘要

PURPOSE: Provided is a automatic measurement system of acidity of acid rain by separately collecting acid rain according to its quantity, supplying KCl solution into a cell to minimize error caused by pH electrode and transferring measured data through LAN. CONSTITUTION: The automatic measurement system of acidity of acid rain comprises the parts of: a funnel to collect rain; a measuring cell which is fitted to the lower part of the funnel, receives rain, and has a rain gauge, pH electrode and a first valve to control rain flow; and a control panel to control the first valve and to transfer measured data to PC through LAN.
