±2000mV Online ORP sensor electrode for sewage water

In nature, many microbial enzyme-catalyzed reactions are redox reactions. Through the transfer of electrons in the reaction, one compound is oxidized and the other is reduced. ORP measurement can reflect the changes in dissolved oxygen in the water body and provide us with pollution information of the water body. Sewage treatment is mainly a process that uses natural microorganisms to remove various organic and inorganic substances in sewage through oxidation-reduction reactions. Then by detecting the oxidation-reduction potential of the sewage, the oxidation-reduction property of the sewage can also be reflected. The sewage ORP analyzer is an instrument used to measure the oxidation-reduction potential ORP in sewage. Its main principle is to evaluate the redox status of dissolved substances in sewage liquid by measuring its potential. ORP sensors electrodes are widely used in municipal sewage, industrial wastewater, ponds, rivers and oceans. It is used to monitor and detect the quality of water to help water treatment plants and environmental protection departments control water pollution and treatment. The ORP Sensor probe is the core part of the ORP analyzer and is usually made of precious metals such as gold and platinum. When the ORP electrode comes into contact with the liquid, it measures the potential difference and converts the value through the transmitter into an ORP value that can be read.

3. The ORP electrode reference adopts a large-area annular porous PTFE diaphragm, which has fast penetration speed and is not easy to block.
4. Double salt bridge system, Ag/AgCl reference electrode, stable and reliable measurement

Specification

The level of ORP value is mainly related to the following factors:
The DO value is the most direct cause of the increase in the system ORP value. In pure water, the ORP value has a linear relationship with the logarithm of the DO value, and the ORP value increases with the increase of the DO value.
pH value is an important factor causing the increase or decrease of ORP value. The higher the pH value, the lower the ORP value. The lower the pH value, the higher the ORP value.
Changes in temperature can also lead to changes in pH, gas solubility, biological activity, and changes in the phase balance of water pollutants, thereby affecting the ORP value. The higher the solution temperature, the lower the ORP value of the solution;
The higher the activity of microorganisms, the faster they consume oxygen and produce reducing substances, and the faster the ORP value decreases.

ORP is an important direction for the development of automatic control technology and anaerobic precision control in sewage treatment plants. It is of great significance for saving energy, controlling the metabolic pathways of anaerobic microorganisms, and improving treatment effects. ORP electrodes are widely used in sewage plants, wastewater treatment, water plants and other occasions.?
