CLF/CLT10SC Промышленный анализатор свободного/общего хлора (электродный метод)

Principle of Operation:

• Amperometry is an electrochemical technique that measures the change in current caused by a chemical reaction occurring at an electrode, and the resulting current is proportional to the concentration of the analyte. A conventional amperometric sensor consists of two different electrodes—an anode and a cathode (e.g., silver/platinum or copper/gold, respectively).

• In contrast, the CLF10sc and CLT10sc online free (total) chlorine analyzers use a three-electrode amperometric system, in which the anode is divided into two parts—a reference electrode and an auxiliary electrode (or counter electrode). These systems are usually supported by special circuitry and direct a voltage between the two electrodes. The three-electrode design of the HACH free chlorine analyzer makes online free (total) chlorine measurement more stable and extends the service life of the working electrode and reference electrode.
