Product Description
DWS-51 Laboratory Sodium Meter
DWS-51 Sodium Ion Concentration Meter is designed for measuring the sodium ion content in aqueous solution, especially suitable for the quality monitoring of high-purity water in the power plants (such as steam, condensate water, boiler feed water, etc.). It can also be used for measuring the sodium ion concentration in the natural water and the industrial drainage in high education institutions, research institutes, petrochemical industry, microelectronics industry, etc.
Features
DWS-51 Sodium Ion Concentration Meter adopts the single-chip computer technology, featured by the simple and convenient operation as well as the intuitive and accurate digital display.
The instrument has the manual temperature compensation and the automatic temperature compensation functions(When it accesses to the temperature electrode, it enters the automatic temperature compensation and displays the current temperature; when it does not access to the temperature electrode, the instrument enters the manual temperature compensation and displays the manually set temperature value.)
In addition to pNa value display, the instrument also has the function of sodium ion concentration [Na+] display function.The external shape of the instrument is compact and beautiful.
