CALIBRATION METHOD FOR WATER QUALITY MEASURING INSTRUMENT AND CALIBRATING MIXED STANDARD SOLUTION

摘要

PROBLEM TO BE SOLVED: To provide a calibration method for water quality measuring instrument capable of easily and precisely calibrating a water quality measuring instrument equipped with a plurality of sensors at a low cost. SOLUTION: This calibration method for the water quality measuring instrument equipped with a plurality of sensors 7 and 8 for measurement of water quality comprises performing the two-point calibration including zero-point calibration of the sensors 7 and 8 by use of two kinds of mixed standard solutions A and B.
