Conductivity sensors

Our broad range of conductivity cells encompasses three measuring techniques:

  • 2-electrode cells for µS/cm ranges
  • 4 and 6 electrode sensors for mS/cm ranges
  • non-contact, electrode-less sensors.

Multi-electrode and electrode-less (toroidal) sensors tend to be used for applications with aggressive chemicals or where there can be sensor coating or fouling.

Our offering

2-electrode, contacting, conductivity cells

 
Range 0 to 10,000 µS/cm (0 to 20,000 µS/cm using TB82TE analyzers)
 
High accuracy technique for trace conductivities from ultrapure water to industrial rinse waters. An alternating current is passed between two electrodes in contact with a solution. The transmitter converts the resultant potential difference into conductivity, concentration or specific resistance.
