B&C Electronics SZ 283

This sensor is made for the measurement of free chlorine, chlorine dioxide and dissolved ozone in water.

The potentiostatic method is an “amperometric” measure with constant potential, made through 2 metal electrodes and a reference electrode dipped in a cell. The current running through the cell consumes Chlorine or Ozone contents, therefore they must be renewed through a constant liquid flow. In the traditional amperometric measurement it results difficult to maintain a constant relation between cell current and Chlorine (Ozone) concentration, especially near the zero, because of the ORP and liquid resistance effects. As result frequent zero and sensitivity calibration are needed. In the potentiostatic measuring, the electrodes potential is electronically controlled in relation to the liquid, providing a linear relationship current/concentration and a very stable zero value in oxidative absence.
