Conventional universal conductivity measuring cells
WTW sensors universal conductivity measuring cell TetraCon® 325
WTW sensors universal conductivity measuring cell TetraCon® V
WTW sensors universal conductivity measuring cell KLE 325

Conductivity measuring cells with graphite electrodes in two and four pin models for standard measurements in aqueous solutions in the field and in the lab

  • No measuring errors due to cable, polarization effects or changes of the electrical edge field
  • Highest precision and linearity
  • Long-term stable cell constant thanks to graphite electrodes

The universally usable conductivity measuring cells by WTW set standard in the conductivity measurement. Their 4 electrode technology makes them insensitive to pollution, uninfluenced by polarization effects and therefore precise and reliable in any conditions. For simple applications, there is a cost-effective 2 electrode cell with graphite electrodes available.
