PURPOSE: A system is provided to achieve an improved efficiency of measuring while allowing data collection and analysis to be performed in a convenient way. CONSTITUTION: A system is characterized in that a concentration of hydrogen ion, concentration of a variety of ions, oxidation-reduction potential(ORP), and a temperature can be measured simultaneously through six channels, a computer controls for such a measurement, and the measured data is collected and analyzed by the computer. The channel can be extended into thirty. A concentration of hydrogen ion, concentration of a variety of ions, ORP, and temperature are read from a sensor, and the read data is amplified and converted into digital signal and transmitted to a computer through an input/output unit(RS232C). The computer performs temperature compensation and operation for the received data. The computer outputs a command for correction/measuring and has a function of real-time data collection. Thus-obtained data can be stored in file or printed through a printer.
