DUC2-PR Online Digital PH/ORP Controller

pH value is one of the important factors affecting water quality. It affects the form and solubility of dissolved substances in water quality. pH is an indicator of the acidity and alkalinity of water. When the pH value is 7, it means neutral, when it is less than 7, it is acidic, and when it is greater than 7, it is alkaline. The pH value of natural surface water is generally between 6 and 9. When algae grow in the water body, they absorb carbon dioxide due to photosynthesis, which will cause the surface pH value to increase. By continuously monitoring the pH value, the acidity and alkalinity staus of the water body can be understood in a timely manner, the water quality status can be assessed, and necessary treatment and management measures can be taken. ORP value is another important indicator for ssurface water monitoring. Oxidation-reduction potential value has an important impact on the health of aquatic organisms and ecosystem. By continuously monitoring ORP values, the accumulation or abnormal changes of harmful substances in water bodies can be detected early and the stability and diversity of the ecosystem can be protected. So how do you monitor the pH or ORP of surface water? The DUC2-PR online pH/ORP controller developed and produced by Delfino is an instrument that supports the connection of digital pH or ORP sensors. It is specially designed for digital sensors. It is a single-channel controller which is widely used in water treatment plants, chemical industry, food and beverage industry, environment monitoring, swimming pools and other occasions where continuous monitoring of water pH is required.

Specification

With the rapid development of industrialization and urbanization, water pollution problems are becoming increasingly serious. Surface water is an indispensable part of human life and ecological system, and its water quality is directly related to public health, agriculture production, ecological balance and other aspects. In addition to pH value, the water quality evaluation indicators of surface water include dissolved oxygen, permanganate index, BOD, chemical oxygen demand, ammonia nitrogen, total phosphorus, copper, zinc, fluoride, etc. Effective water quality monitoring of surface water using online water quality instruments is not only a need for environmental protection, but also an important guarantee for the sustainable development of human society. The online pH/ORP controller is connected ti a digital pH sensor or ORP sensor, which can continuously monitor the pH or ORP value of water quality. The data is accurate, stable and has a long service life. If you want to monitor other values besides pH value, you can use our MCC200 series multiparameter water quality analyzer. Delfino focuses on the R&D and production of water quality analysis instruments. Our main products include pH ORP analyzer, conductivity analyzer, turbidity analyzer, COD analyzer, dissolved oxygen analyzer, ammonium analyzer, chlorine analyzer, etc.
