Model S80 Intelligent Sensors
Electro-Chemical Devices offers a complete line of liquid analytical sensors: pH, ORP, Specific Ion, Dissolved Oxygen, Conductivity & Resistivity. The technical advantage of the Model S80 Intelligent Sensors are the 6 points of design flexibility to configure a sensor that best fits your application. The S80 sensors have two Universal Sensor Designs; Insertion/Submersion or Valve Retractable with flaired end to prevent blow out. The standard Model S80 sensors have a rugged ¾” O.D. 316 stainless steel body with a 10 '. cable or an optional waterproof detachable cable
assembly.
Advantages:
- Intelligent sensor design with digital communication
- Calibration data is stored in the sensor allowing field installation of a pre-calibrated sensor.
- Detachable cable option simplifies the installation of pre-calibrated sensors.
- Multiple individual measurement parameters in the same mechanical configuration- pH, ORP, Specific Ion, Dissolved Oxygen, Conductivity & Resistivity
- Readily available application specific electrode cartridges. Many unique pH electrode design formulations and materials of construction which are field proven and selected for long life and accuracy. Long life replaceable electrode cartridges lower the over all operating cost.
- Submersible and Retractable Sensors Various process fitings with adjustable insertion lengths - threaded fitings, sanitary fitings, flanges and valve retractable fitings. Industrial housing materials for compatibility with process fluid. Stainless Steel, Titanium, Hastelloy C-22, Polypropylene or PVDF (KynarTM). Standard 10” or 17” lengths additional lengths available.

Model S80 Intelligent Sensors
Ion selective 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 activity (concentration) 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 concentration 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 concentration. Most pIon sensors are subject to interfering ion errors. A positive interference caused by similar ions in the solution. Consult with the factory on
all new installations to determine the suitability of the measurement.
