DWS - 803 Chinese desktop sodium degree program

DWS - on market 803 to use the most convenient and strongest function one of sodium degree program. Deserve PPB specially for the laboratory level sodium ions electrode and reference measurement than electrodes, in the performance of the static measurement beaker than traditional sodium table has greatly improved, just in use note electrode can be cleaned, completely is satisfactory. Can be widely used in thermal power, chemical fertilizer, metallurgy, environmental protection, pharmacy, biochemical, food and water and other solution sodium ions monitored continuously.
