Introduction
♦ Sodium Ion Sensor is used to measure concentration of sodium ion in solution. It measures using datalogger and software.
Usage
♦ Take out electrode cover. Rinse it using distilled water. Dry it using filter paper.
♦ Connect electrode to sensor, datalogger and computer.
♦ Open SWR iLab. The sensor has been calibrated before manufacturing. Immerse the electrode into solution to collect data. Wait until the electrode is stable to record data.
♦ Rinse the electrode using distilled water after measuring. Dry the electrode using filter paper. Cover the electrode and preserve it in bag.
Notes
♦ H+, K+ and NH4+ are able to interrupt the electrode. Be careful when measuring.
♦ Use 0.2mol/L diisopropylamine to adjust the pH value of solution to 10. It can prevent the interruption from H+.
♦ If it is left unused for a long time and electrode can not touch internal solution, you should swing the electrode so that internal solution flows back to top of electrode. Immerse the electrode in solution with pNa=4 for more than 8h.
♦ Immerse the electrode completely in the solution to be measured during measuring.
♦ Keep the electrode wire and insulation part clean and dry.
