DCL chlorine dioxide diaphragm probe
The sensor is compatible with the presence of surfactants.
Measurement range:
- 0 ÷ 2 ppm
- 0 ÷ 20 ppm
SONDA DCL chlorine dioxide diaphragm probe for measuring chlorine dioxide in water, supplied with electrolyte, used in automatic Etatron water treatment stations. For an accurate reading, the operating value the pH level should remain unchanged. The sensor can be used in water with surfactants (Surfactant), flocculant. The connecting cable is not included.
Design and operation of the SONDA closed-type amperometric (potentiostatic) probe DCL is a closed galvanic cell (like a battery), which has a cathode (from gold or platinum) and anode (silver or copper). For automatic temperature compensation of readings electrodes, built-in liquid temperature sensor. The cell is filled with electrolyte and separated from the measured medium membrane that prevents the loss of electrolyte and allows only the composition of the measured liquid, is also a filter from unnecessary and harmful impurities. Everything that the membrane passes is a source generation of current on the sensor electrodes. The filtered membrane composition enters the electrolyte filling the sensor, where 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 water, the level of which was to be measured. Into the case a microcircuit is built-in that processes the current coming from the electrodes and the built-in temperature sensor, converts it into voltage (potential) suitable for handling reagent dosing by the controller
