Conductivity Sensor

The conductivity cell consists of a quartz glass cylinder with 7 platinum coated ring electrodes. Because of the small inner diameter of 8 mm the cell needs a minimum vertical flow velocity to obtain full accuracy. The cleaning procedure must be carried out very carefully, hence the glass cylinder is very sensitive against shock and impact
