FIC free chlorine sensors

Amperometric inorganic free chlorine sensors FIC

Measurement range:

  • 0.05-2 ppm
  • 0.05-20 ppm
  • 0.05-200 ppm

FIC chlorine sensor for measuring inorganic free chlorine in water, supplied with electrolyte, used in ETATRON D.S. automatic water treatment plants. (Italy). For accurate readings, the working pH should remain unchanged. The sensor can not be used in water with: isocyanuric acid, surface-active substances (surfactants), flocculant. Connecting cable not included.

Design and operation of the closed-circuit ammeter FIC - 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)
