IQ Sensor Net System IQ Sensor Net TetraCon® Conductivity Sensor

700 IQ/SW
Overview Specifications Documentation & Tools ;


WTW TetraCon Conductivity Digital IQ sensor for wastewater treatment plants, connectable to the IQ SENSOR NET. TetraCon® 700 IQ – digital 4 electrode conductivity measuring cell with flow-free operation, especially with high conductivity.

Product Features
  • Rugged electrode-style conductivity probe for the IQ Sensor Net 
  • Flat surface reduces fouling
  • Large measurement range; 10 µS/cm.....500 mS/cm
  • Integrated NTC temperature sensor for temperature compensation
  • 2-year warranty on the probe
  • Highest linearity and very insensitive against contamination by 4-electrode system

This measuring technique has proven itself over the years and offers an interference-free operation, also and foremost at high conductivity values. The 4-electrode measuring cell is very insensitive to contamination. Based on the pressure resistance of up to 10 bars, there is nothing to stop you from mounting into pipes or on lines.

The sea water model includes the sensor for use in special media: All wetted parts are made of titanium and plastic and are therefore extremely resistant to corrosion.
