Model S80 Potassium Ion Sensors

The Model S80 universal sensors provide a stable and economical platform for the in line measurement of pH, ORP, Specific Ion, Dissolved Oxygen, Conductivity or Resistivity. The Model S80 is an insertion or immersion style sensor for use in pipe Tees or on the end of a Stand Pipe for immersion into a tank or pond. The Model S80 is also available as a valve retractable design allowing insertion or removal of the sensor into a pipe without interrupting the process flow. Both sensor designs use easily replaceable electrode cartridges. ECD offers several ion selective electrode cartridges suitable for continuous online measurement.

The Potassium Ion Electrode is a combination electrode with a sensing element made of a PVC membrane containing an ion selective ionophore, valinomycin, and a double junction reference electrode. The Potassium Ion Selective Electrode cartridge develops a millivolt potential proportional to the concentration of potassiumions in the measured solution. The typical output is 50mV to 60mV per decade of change in concentration. The Potassium Ion sensors are used with the Model T80 Transmitter with its dual channel mix and match capabili.es The analyzer will measure potassium ions from 20 ppb to 39,000 ppmin the optimum pH range of 4-11 pH. In the acidic solutions the potassium ion electrode, K+, is interfered by the hydrogen ions, H+, and in alkaline pH solutions, above pH 11, the active ionophore in the membrane is attacked by the caustic deminishing response and destroying the electrode. For measurements below 1 ppm potassium the pH of the solu.on should be above pH 4.5.
