<P>PROBLEM TO BE SOLVED: To provide a system for monitoring water quality for automatically monitoring a plurality of samples which have different water qualities, using one measurment apparatus. <P>SOLUTION: For acquiring calibration data, the remaining nitrogen concentration of water in a hot spring bath 1a is measured by a sensor 12 by opening a solenoid value 11a, and an obtained measurement value X is stored at a measurement value storage section 16 for calibration as a measurement value Sa for calibration. The remaining nitrogen concentration of water passing through the sensor 12 is simultaneously inspected by a DPD method, and the obtained inspection value is accommodated at a concentration inspection value storage section 19 as a concentration inspection value Ka. The solenoid valve 11a is opened in normal monitoring, and the water in the hot spring bath 1a is measured by the sensor 12. Then, the obtained measurement value X is given to a nitrogen concentration calculation section 15 and is calibrated by the measurement value Sa for calibration and the concentration inspection value Ka, and thus a concentration value Y, corresponding to the inspection result by the DPD method, is calculated. <P>COPYRIGHT: (C)2006,JPO&NCIPI |
