Sodium ion concentration meter DWS-51
Sodium ion concentration meter DWS-51
Product details
DWS-51The sodium ion concentration meter is designed to measure the sodium ion content in aqueous solutions, especially for quality monitoring of high-purity water (such as steam, condensate, boiler feedwater, etc.) in power plants. It can also be used in higher education institutions, research structures, petrochemicals, microelectronics and other departments to determine the sodium ion concentration (or activity) in natural water, industrial wastewater and other water.
2Characteristics of the instrument
●DWS-51The sodium ion concentration meter adopts single-chip technology, which makes the operation simple and convenient, and the digital display intuitive and correct.
●The instrument has manual temperature compensation and automatic temperature compensation functions (when the temperature electrode is connected, the instrument enters automatic temperature compensation and displays the current temperature; when the temperature electrode is not connected, the instrument enters manual temperature compensation and displays the manual temperature setting value). The temperature electrode is an optional key, and if the user needs it, they need to specify it when placing an order.
●The instrument haspNaIn addition to displaying values, it also has sodium ion concentration values[Na+]Display function.
●The instrument has a beautiful and lightweight appearance.
