ORP is an abbreviation for Oxidation-Reduction Potential, also known as Oxidation-Reduction Potential Value. It is an index to measure the redox ability of a solution. The digital ORP sensor developed and produced by Daruifuno has an RS485 digital interface, which can be directly connected to industrial control equipment to output data. It is necessary to monitor the value of ORP in the waterworks, especially in some aspects of water treatment. For example, monitoring the ORP value in raw water can help determine the concentration of oxidizing and reducing substances in the water, as well as whether there are harmful substances. In the process of coagulant dosing, monitoring the value of ORP can help determine the appropriate dosage of coagulant to achieve the best coagulation effect. Similarly, in the flocculant dosing process, using a digital ORP sensor to monitor the ORP value can help determine the flocculant dosage to achieve the best flocculation effect. In the process of chlor…
