Overview of Sodium Ion Concentration Meter:

The DWS-51 sodium ion concentration meter is an instrument and design for measuring the sodium ion content in aqueous solutions, especially suitable for quality monitoring of high-purity water (such as steam, water, boiler feedwater, etc.) in power plants. It can also be used in structural institutions such as universities, scientific research departments, petrochemical industry, microelectronics, determination of sodium ion concentration (or activity) in natural water, industrial wastewater, etc.
