IDS conductivity measuring cells – measurements from pure water all the way to concentrated solutions with proven two and four electrode technology

  • Proven 2 and 4 electrode technology
  • Easiest handling, robust design
  • Wide area of application - from pure water to highly concentrated solutions

WTW has been manufacturing conductivity measuring cells of the highest quality for decades. These are the basis for the new IDS conductivity measuring cells. The advantages of the IDS technology include the automatic transfer of the cell constant and therefore the exclusion of possible erroneous input. There are two models available to cover the entire conductivity range: The four electrode measuring cell TetraCon® 925 for medium and high conductivity , for pure water and for low conductivity, the two electrode measuring cell LR 925/01 including flow container.
