Sander redox measuring and control device for Sander ozonizers of type C, P, S, XT
The device can be used immediately. No calibration is required for the redox electrode. Setting the desired target value is very easy using an adjusting screw (screwdriver is included).
To ensure that the redox electrode functions properly, it must be cleaned at regular intervals or as needed. You can use liquid citric acid (drugstore) for this purpose. An empty bottle is included which can then be filled with the cleaning solution.
The electrode is equipped with a 3 m cable and a plastic holder to attach the electrode to the edge of the pool.
