Product details
Process control system for water quality analyzerBy utilizing the intelligent characteristics of process control analysis instruments and online water quality analyzers, the analysis of ions in water quality is carried out to determine the concentration of ions in the water. The instrument calculates the concentration value and automatically converts the dosing time. It has the function of automatic dosing and can automatically adjust the ion content in the water quality. The monitoring indicators for the industry types are as follows.
