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 Chloride Ion Electrode is a combination electrode with a silver Chloride/silver sulfide (AgCl/AgS) solid state pressed crystal sensing element and a double junc.on reference electrode. The Chloride Ion Selective Electrode cartridge develops amillivolt potential proportional to the concentration of chloride ions in themeasured solution. The typical output is 54mV to 60 mV per decade of change in concentration. The
speed of response varies from a few seconds in concentrated solutions up to a few minutes in the lower ppm ranges. The Chloride Ion sensors are used with the Model T80 Transmitter with its dual channel mix and match capabilities. These analyzers will measure chloride from 2.0 ppm to 35,500 ppm autoranging the display between the ppb, ppm and ppt (parts per thousand) scales.
