Abstract: A system for calculating a concentration of a water treatment chemical includes a water analyzer, databases storing information regarding a chemical component of the water treatment chemical, a server sending the information stored in the database, and a communication device sending the information acquired from the server to the water analyzer. The water analyzer includes a storage unit storing a calibration curve defining the relationship between the concentration of a chemical component and absorbance, a communication unit receiving the information regarding the chemical component of the water treatment chemical, an irradiation unit irradiating water to be analyzed with light, a detection unit detecting transmitted light, and an arithmetic and control unit calculating absorbance from the result of the detection by the detection unit, acquiring a calibration curve from the storage unit, and calculating the concentration of the chemical component with reference to the acquired calibration curve and the measured absorbance.

Abstract: Provided are a concentration-factor measurement device and method for accurately calculating a concentration factor of circulating water, and a method for measuring a water-quality index value of the circulating water. The concentration-factor measurement device includes a light-absorbance measurement unit (1) for measuring absorbance by irradiating each of cells (12A-12C) with light, and an electrode measurement unit (2) equipped with electrodes (16, 17) that are inserted into a water sample in a container (20). For each item of water quality, the device calculates a concentration factor on the basis of a measured value measured when the water sample (W) is the circulating water, and a measured value measured when the water sample (W) is makeup water. A plurality of concentration factors are calculated on the basis of the measured values for plural items of water quality. Hence an accurate concentration factor can be obtained.
