Overview

DWS-803A is specifically designed for laboratory ppb level sodium ion measurement electrodes and reference electrodes. Its static measurement performance in a beaker is greatly improved compared to traditional sodium meters. As long as the electrode is cleaned carefully during use, satisfactory results can be obtained. It can be widely used for continuous monitoring of sodium ions in solutions such as thermal power, chemical fertilizers, metallurgy, environmental protection, pharmaceuticals, biochemistry, food, and tap water.
