  • Page 4: General Description

    1.-GENERAL DESCRIPTION Free chlorine amperometric sensor for drinking water and water treatment. Specifically designed to determine the residual level of inorganic chlorine in water. The chlorine sensor is of the open cell type with no intermediate liquids for the electroche- mical reaction, thus facilitating installation and maintenance.

  • Page 5: Technical Features

    3.-TECHNICAL FEATURES - Potentiostatic amperometric sensor for measuring free chlorine - Analyzable products: Cl , NaClO, Ca(ClO) - Four- electrode system: Working Electrode (Au) Reference Electrode (Ag/AgCl) Counter electrode (Au) GND Electrode (Au) -Scale reading 0.02-3.00 mg/l - Precision: ± 2% - WorKing conditions: pH 6.5-9.0 Temperature 0-40ºC...

  • Page 6: Operation

    4.-OPERATION Amperometric analysis is based on the measurement of current intensity. This intensity is produced by the oxidation or reduction of an analyte when a suitable voltage is applied. In the case of free chlorine analysis: HClO + H + 2e Cl + H O As can be deduced from the above reaction, current intensity is proportional to the amount of hypochlorous acid which is present in the measured solution.

  • Page 7: Installation

    5.- INSTALLATION The sensor must be installed where it is possible to ensure a constant flow of water with no chance of air bubbles forming in the measuring cell. It is recommended that it be installed in the Multifunction Sensor Holder (Ref. 44-020), especially designed for this application, and equipped with the following:...

  • Page 8: Start-Up

    6.- START-UP 6.1 SENSOR CONDITIONING If it has not been used recently or if it is being connected for the first time, the sensor will require a conditionning time. Prior to sensor calibration, insert the sensor correctly into the sensor holder and let the water containing free chlorine flow for 24 hours to ensure that the cell is properly polarized.

  • Page 9: Maintenance

    7.- MAINTENANCE 7.1 CLEANING AND CALIBRATION Cleaning interval: Every 8 hours and after working for several hours without flow, with water without free waste chlorine, or over 3 mg/l. This cleaning frequency is maintained automatically with the WTR PRO control device. Calibration interval: The first time, after 24 hours.
