This conductivity cell is designed to dip directly in the sample and test low conductivity samples. Measurement range of 0.1 μS/cm to 10 mS/cm.This conductivity cell is designed to measure low conductivity water such as deionized water and regular drinking water. It is a submersible type which sits directly in the sample for a direct reading. It requires 50 mL of sample and can help determine the quality of drinking water. The conductivity of a sample is often a good indication of the total dissolved solids present in a sample, and therefore more pure water will give a lower conductivity reading. For example, the conductivity of sea water is much higher than that of deionized water because it has many dissolved solids present.
