Peracetic Acid Sensor PA

SONDA PA sensor for measuring peracetic acid

The sensor is compatible with the presence of surface-active substances (surfactants)

Measurement range:

  • 0 ÷ 200 ppm

Membrane probe (sensor) SONDA PA PES7H - is necessary for measuring peracetic acid in water, supplied with electrolyte, is used in automatic processing stations water Etatron. The electrical conductivity of acids does not affect the measurement results. Compatible with the presence of surfactants in water. A connecting cable is not included, a non-standard sensor holder is required (on request).

Design and operation of the amperometric (potentiostatic) closed-type sensor SONDA PA - 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 the voltage suitable for processing by the controller of the dosage of reagents into voltage (potential).
