DCL Chlorine Dioxide Membrane Probe

SONDA DCL Chlorine Dioxide Membrane Probe

The sensor is compatible with the presence of surfactants.

Measurement range:

  • 0 ÷ 2 ppm
  • 0 ÷ 20 ppm

SONDA DCL chlorine dioxide membrane probe for measuring chlorine dioxide in water, supplied with electrolyte, used in Etatron automatic water treatment plants. For accurate readings, the working pH should remain unchanged. The sensor can be used in water with surface-active substances (surfactants), flocculant. Connecting cable not included.

The design and operation of the SONDA DCL closed-type amperometric (potentiostatic) probe is a closed galvanic cell (similar to a battery), which has a cathode (in gold or platinum) and an anode (silver or copper). For automatic temperature compensation of the readings of the electrodes, a liquid temperature sensor is integrated. The cell is filled with electrolyte and separated from the medium by a membrane, which prevents the loss of electrolyte and allows only the composition of the liquid to be measured to be measured, which is also a filter from unnecessary and harmful impurities. All that the membrane passes is a source of current generation on the sensor electrodes. The filtered membrane composition enters the electrolyte filling the sensor, where it decomposes at the cathode. The formed ions enter the anode, where they are oxidized - a current arises proportional to the concentration of the analyte in the water, the level of which was necessary to measure. A microcircuit is integrated in the housing, which processes the current coming from the electrodes and the built-in temperature sensor, converts suitable voltage for potential processing of the reagent by the controller into voltage (potential)
