Ion selectve electrodes are not limited to laboratory use; some are suitable for con6nuous online measurement. ECD offers Specific Ion Electrode cartridges to measure the various ions listed below. Specific Ion electrodes measure the ac6vity (concentra6on) of the ion in solu6on, the “free” ion, not a complexed version. Cyanide, Fluoride and Sulfide ions only exist in a specific pH range as free ions and outside this pH range some percentage of the total concentra6on is complexed as H(X) which is not seen by the sensor. These measurements can be pH compensated using the dual channel transmitter or controller with a pH sensor to determine the total ion concentra6on. Most pIon sensors are subject to interfering ion errors. A posi6ve interference caused by similar ions in the solu6on. Consult with the factory on all new installa6ons to determine the suitability of the measurement.

The S80 Insertion Sensor uses a ¾” MNPT compression fitting as the process connection. This allows a variable insertion length to accommodate installation in pipe tees, flow cells, or through tank walls. If the fitting is reversed the sensor can be installed in a stand pipe for submersion into a tank.

The S80 Valve Retractable Sensor uses a 1” ball valve with a 1” NPT process connection. Loosening the rear compression fitting allows the sensor to slide freely through the ball valve but stop at the compression fitting for either insertion into the process or retraction from the process.
