The sensor is compatible with the presence of surfactants.
Measurement range:
Potentiostatic hydrogen peroxide sensor WP7HUn SONDA HP - required for measuring hydrogen peroxide in water, supplied with electrolyte, used in automatic Etatron water treatment stations. Compatible with the presence of surfactants in the water. Connection cable not included, required non-standard sensor holder (on request).
Design and operation of the SONDA closed-type amperometric (potentiostatic) sensor HP - is a closed galvanic cell (like a battery), which contains 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.
