Peracetic Acid PA Sensor

Датчик надуксусной кислоты PA

The sensor is compatible with the presence of surfactants (surfactants)

Measurement range:

  • 0 ÷ 200 ppm

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

Design and operation of the amperometric (potentiostatic) closed-type sensor SONDA PA - is a closed galvanic cell (like a battery), which has a cathode (gold or platinum) and anode (silver or copper). For automatic temperature compensation electrode readings, built-in liquid temperature sensor. The cell is filled with electrolyte and is separated from the measured the environment with a membrane that prevents the loss of electrolyte and allows only the composition necessary for measuring the measured liquid is also a filter from unnecessary and harmful impurities. Everything that the membrane passes through is is a source of current generation at the sensor electrodes. The filtered membrane composition enters the filling electrolyte sensor where it decomposes at the cathode. The resulting ions go to the anode, where they are oxidized - there is a current proportional to the concentration of the analyte in water, the level of which was necessary measure. A microcircuit is built into the case that processes the current coming from the electrodes and the built-in sensor temperature, converts into a voltage (potential) suitable for the controller to process the dosage of reagents.
