IP68 Industrial Online Digital ORP Sensor for Wastewater

ORP denotes the oxidation-reduction potential of a solution. The ORP value is a measure of the oxidation-reduction capacity of an aqueous solution, and the unit is mV. The Digital ORP Sensor consists of an ORP composite electrode and a mV meter. The ORP electrode is an electrode that can absorb or release electrons on the surface of its sensitive layer. The sensitive layer is an inert metal, usually made of platinum and gold. The reference electrode is the same Ag/AgCl electrode as the pH electrode. The DRH790 online digital ORP Sensor developed and produced by the Daruifuno brand is widely used: the treatment of industrial wastewater, especially the wastewater generated in some metal finishing processes, and the important oxidation-reduction reaction in municipal sewage treatment systems. Using the online digital ORP sensor can continuously monitor the ORP value of water quality in real time, without sampling and measuring in the laboratory, which can greatly shorten the testing process and improve work efficiency in terms of time. Compared with the analog ORP, the digital ORP electrode can directly output data without a controller or transmitter, which is convenient for networking.

About water quality ORP value
In natural water bodies, there are many kinds of ions and dissolved oxygen with varying prices. When some industrial sewage is discharged into the water, the water contains a large amount of ions and organic substances. Due to the different properties of the ions, oxidation-reduction reactions occur in the water body and tend to Therefore, in the natural water body, it is not a single redox system, but a mixed redox system. What the measuring electrode reflects is also a mixed potential, which has a large experimental error. In addition, the pH value of the solution will also affect the ORP value. Therefore, it is meaningless to emphasize the excellent potential of the solution during the measurement of the reagent. We measure the ORP value of the solution through a digital ORP sensor, which indicates a reduction or oxidation state of the solution near a certain value, or a certain property of the solution (such as hygiene, etc.), but this value will be larger It is not possible to make a quantitative determination of it, which is different from the accuracy in pH testing. Regarding the temperature of the digital ORP sensor, we only provide temperature detection, because the temperature coefficient affecting the ORP value is a variable and cannot be corrected, so the ORP electrode usually does not have a temperature compensation function.
