[0002] With the continuous development of industrial production, circulating cooling water systems are widely used in many fields due to their high efficiency and energy saving characteristics. However, circulating cooling water is prone to scaling and corrosion during use, which not only reduces the system's heat transfer efficiency but may also lead to equipment damage, increased maintenance costs, and energy consumption. Circulating cooling water treatment agents, such as scale inhibitors, corrosion inhibitors, and descaling agents, can effectively alleviate these problems and improve the system's operating efficiency and reliability.

However, existing testing devices suffer from several shortcomings: they are limited in function, only capable of testing specific performance aspects; they are complex to operate, requiring significant time and manpower; and they cannot simulate various real-world operating conditions, leading to discrepancies between test results and actual application scenarios. These limitations render existing testing devices inadequate for meeting practical needs, necessitating an advanced testing device capable of comprehensively evaluating the performance of circulating cooling water treatment agents.
