EC250 Electrical Conductivity Sensor

The EC250 Electrical Conductivity Sensor provides highly accurate conductivity measurements in a wide range of hydrological applications.


  • Toroidal sensing technology eliminates electrode corrosion effects guaranteeing long life and reduced field service
  • On-board temperature measurement and microprocessor controlled temperature compensation and linearization ensure highly accurate readings in demanding conditions
  • Separate conductivity and temperature outputs
  • Raw conductivity or on-board normalisation of conductivity to 25°C


  • Operation on remote power source for long periods
  • High reliability means critical measurements are not lost through sensor down time
  • Low cost of ownership and minimal maintenance
  • Ease of use and long term reliability
