Automatic water analyzing apparatus

Abstract

Abstract PURPOSE:To measure a plurality of measuring item simultaneously, automatically, and accurately, by operating and outputting the detection of measured components based on the outputs of a plurality of sensors corresponding to each measured component of water to be checked and a temperature sensor and a table of a plurality of analytical curves, which are changed by temperatures, pH, electric conductivity, and the like. CONSTITUTION:The signals corresponding to temperatures, pH, electric conductivity, and concentration from a temperature sensor T provided in water to be checked and a plurality of sensors S1-Sn corresponding to each measured component of the water to be checked are inputted to a CPU22 through amplifiers A0, A1-An, a multiplexer 20, and an AD converter 21. The CPU22 performs operating processing by using analytical curves with regard to temperature, pH, electric conductivity, and concentration and the input signals. The detected values of a plurality of measuring items are outputted to a liquid crystal display device 25 and a printer 26. Opening and closing of a plurality of valves V1-Vn are controlled in correspondence with the detected values, and the amount of supply of correcting liquid is adjusted.
