Key Features
  • Measures Cl- in freshwater applications
  • Depths not to exceed 17 meters (55 ft) or 25 psi
  • 3 month warranty on sensing module

The ProDSS ion-selective electrode (ISE) chloride sensor uses a solid-state membrane attached to a conductive wire. The internal solution is separated from the sample medium by a polymer membrane, which selectively interacts with chloride ions. When the sensor is immersed in water, a potential is established across the membrane that depends on the relative amounts of ions in the sample and the internal solution. This potential is read relative to the Ag/AgCl reference electrode.

Questions & Answers
Can the YSI ProDSS chloride sensor log data internally at various intervals in the field without an operator present?
The ProDSS is intended for spot sampling rather than for unattended logging. If you need instruments that can be deployed for extended periods and collect internal data, consider the EXO sonde series from Xylem or the MX series from HOBO.
