pH meter consists of two parts: a sensor and a secondary instrument. It can be equipped with three composite electrodes or two composite electrodes to meet a variety of applications. It is equipped with a pure water electrode, which can be used to measure the pH value of water with electrical conductivity less than 3 μs/cm (such as chemical feedwater, saturated steam, condensate, etc.). The pH value of sewage can be continuously measured and controlled, which is suitable for urban sewage treatment plants, the chemical industry, printing and dyeing, paper making, pharmaceutical, electroplating, and environmental protection. According to the environment and characteristics of the water industry combined with international power supply standards, considering the electrical design specifications of the special environment, the addition of **0V AC and safe low voltage *4V AC,*4V DC power supply options.
