water crisis is a serious problem faced by all countries in the world, and desalination is one of the important ways to solve the water crisis. At present, countries around the world generally attach great importance to the development of seawater utilization and seawater desalination technology. 70% of the freshwater resources in Middle Eastern countries such as Saudi arabia, the united Arab Emirates, and Israel come from seawater desalination. Developed countries such as the United States, Japan, and Spain are also activity developing the seawater desalination industry. Conductivity is and important parameter that characterizes the conductivity of a solution. It is one of the most commonly used and important parameters in water quality testing. The conductivity parameter is an important indicator to ensure the normal operation of the seawater desalination system and to measure the quality of the desalinated water. There are two measurement methods of conductivity snesors…
