Description

CDT-14A ORP Sensor

Analog orp sensor offers a simple and cost-effective solution for a diverse range of waste water and process applications. It has the remarkable advantage of being an all-in-one sensor that enables the simultaneous measurement of ORP and temperature. This makes it highly convenient and efficient in various industrial and environmental settings.

The sensor’s design is also quite remarkable. The rugged Ryton body, for instance, is specifically engineered to ensure easy installation into on-line systems. It features 3/4 inch tapered threaded connections on both ends of the sensor, which simplifies the setup process.

Application

Water treatment:

◉In drinking water treatment, ORP (REDOX potential) sensors can be used to assess the REDOX status of water quality. For example, during disinfection, common disinfectants like chlorine gas and chlorine dioxide change the ORP value of water.

◉ORP sensors are important monitoring tools in wastewater treatment plants. In the aerobic biological treatment stage, microbes break down organic matter. This process needs an aerobic environment. The ORP value is usually between +200 and +600 mV.

◉In industrial circulating water systems, analog orp sensor are used to prevent corrosion and scaling of equipment. Dissolved oxygen and other oxidizing substances in water can cause reactions on metal surfaces. This can lead to corrosion. By monitoring ORP values.

Aquaculture:

◉In aquaculture ponds, ORP sensors can monitor the REDOX status of the water body in real time. The right ORP value is one of the key factors for the success of aquaculture.

◉The REDOX potential in aquaculture water is closely related to the material circulation and energy flow of the ecosystem. For example, ORP values affect the nitrogen cycle in water. Under aerobic conditions (high ORP), nitration converts ammonia nitrogen to nitrate nitrogen. Under anaerobic conditions with low ORP values, denitrification may occur, converting nitrate nitrogen into nitrogen gas and releasing it into the atmosphere.

Environmental monitoring:

In monitoring rivers and lakes, ORP sensors help check the ecological health of these water bodies. ORP values are closely related to biogeochemical cycles in water bodies. In eutrophic lakes, algae blooms occur. At night, algae use oxygen in the water. This reduces the oxygen reduction potential (ORP).

◉ORP values can also reflect the interaction between surface water and groundwater. In some wetland and river areas, surface water and groundwater mix. This mixing will change the REDOX state of the water.
