The DWL-A sodium ion concentration meter is designed based on the Nernst equation combined with computer technology. The instrument is based on the MCS-51 microcontroller, which controls the entire analysis process, collects and processes data, calculates and displays the concentration of sodium ions. The instrument has the advantages of flexible operation, user-friendly interface, and diverse methods.
