Model:

SL1-DWS-51 sodium ion concentration meter is a kind of electrochemical instrument, which is used to measure sodium ion content in the aqueous solution. It is applied in universities and colleges, research institutes, petrochemical industry and micro-electronics to measure sodium ion concentration (or activity) in different water samples, such as natural water and industrial drainage. It is especially suitable for power plant to make quality monitoring of highly pure water (such as steam, water of condensation and boiler's water supply).
Digital display, direct viewing and accurate measuring result
Manual temperature compensation function.
Besides the display of pNa value, it has sodium ion concentration value [Na+] display function
Beautiful and compact in appearance.
