Ring Platinum Online ORP Sensor Probe Municipal Sewage

Municipal sewage refers to the sewage treated centrally by all urban sewage and industrial wastewater. Urban sewage mainly comes from domestic sewage discharged from households, institutions, businesses, urban public facilities, etc. and an appropriate amount of industrial production wastewater. The wastewater is large in volume and has obvious diurnal and seasonal periodic changes. The main pollutants in sewage include animal and vegetable oils, suspended solids, carbohydrates, proteins, surfactants, nitrogen and phosphorus compounds, microorganisms, etc. Monitoring of ORP value is a basic indicator of municipal sewage, usually made of precious metals such as gold, platinum, and iridium. When the electrode comes into contact with the liquid being measured, it measures the potential difference and converts this value into a readable value. The larger the ORP, the stronger the oxidizing property of the water, and vice versa. The ORP Sensor ASR401V developed and produced by Daruifuno is made of ring-shaped platinum and has a measurement range of ±2000mV, which can meet most water quality ORP measurement needs. For a water body, there are often multiple redox pairs, forming a complex redox system, and its ORP is the comprehensive result of the redox reactions of multiple oxides and reducing substances. Although the value of ORP cannot be used as an indicator of the concentration of certain oxidizing substances and reducing substances, it can help us understand the electrochemical characteristics of water quality, analyze the properties of water bodies, and make prevention or treatment decisions. ORP is a comprehensive indicator.

Specification

ORP analyzers can be used to monitor different types of pollutants and chemicals, including oxidants, reducing agents, preservatives, disinfectants, ammonia nitrogen, sulfates, etc. When treating sewage, it can detect the content of active oxygen and evaluate the efficacy of oxidation and reduction in the sewage treatment system. In addition to the municipal sewage industry, ORP analyzers can also be used to detect food processing, beverage production, agricultural irrigation and other purposes. ORP sensors also need to be calibrated, maintained and cleaned during use to ensure their reliability and accuracy. Secondly, other ions and chemicals present in the water will interfere with the measurement results of the ORP electrode, causing the data values to shift. Therefore, selection is required for different environments. To ensure that the instrument can adapt to complex water quality environments and measurement requirements.

Delfino company focuses on the R&D and production of water quality analysis instruments. Our measurement parameters include pH, ORP, conductivity, TDS, salinity, dissolved oxygen, COD, ammonia nitrogen, turbidity, chlorophyll, blue-green algae, residual chlorine, and chlorine dioxide. wait. In addition to ORP sensors, our main products include pH ORP analyzer, conductivity analyzer, turbidity analyzer, COD analyzer, dissolved oxygen analyzer, ammonium analyzer, chlorine analyzer, etc.

In addition, the measurement of ORP does not require temperature compensation, because when the temperature of the measured aqueous solution changes, the impact on the ORP millivolt value is small. For example, when the solution temperature changes by 5°C, the impact on the ORP is only about 0.5mV, which can be ignored. . Therefore, our ORP electrodes usually do not come with a temperature unit, but if customers want to measure the temperature of water, we can also customize the temperature unit PT1000 or NTC10K.
