Digital dissolved oxygen sensor
Digital dissolved oxygen sensor
- High precision: Digital dissolved oxygen sensors usually have high measurement accuracy and can meet the accuracy requirements of dissolved oxygen concentration measurement in different application scenarios.
- Real-time: The sensor can monitor the changes in dissolved oxygen concentration in water in real time and continuously, providing timely and accurate data support for water quality monitoring and process control.
- Good stability: The use of advanced digital signal processing technology can effectively reduce noise interference and improve the stability and reliability of measurement.
- Easy to maintain: Some digital dissolved oxygen sensors are designed with self-cleaning or self-calibration functions, which reduces maintenance costs and difficulties.
Product Overview：
The digital dissolved oxygen sensor is a sensing device that can measure the dissolved oxygen content in water in real time and accurately. Depending on the type of technology, the digital dissolved oxygen sensor can use different measurement principles. For example, the fluorescence dissolved oxygen sensor determines the dissolved oxygen concentration by exciting the fluorescent substance and measuring the degree of fluorescence quenching caused by the change in oxygen concentration; the electrochemical method uses the oxygen electrode to undergo a redox reaction with the dissolved oxygen in the solution, and determines the dissolved oxygen concentration by measuring the change in current or potential.
This product uses the RS485 communication interface and standard Modbus protocol, with a built-in PT1000 temperature sensor and compensation algorithm, and is suitable for various harsh working environments.
Application：
Water treatment: including drinking water treatment, wastewater treatment, industrial water treatment, etc., used to monitor and control the dissolved oxygen content in water to ensure that the water quality meets the standards.
Aquaculture: In aquaculture, dissolved oxygen concentration is one of the key factors affecting the growth and survival of aquatic organisms. Digital dissolved oxygen sensors can monitor the dissolved oxygen content in water in real time, providing a scientific basis for aquaculture management.
Food and Beverage: In the production process of food and beverage, dissolved oxygen content is one of the key factors affecting product quality. Digital dissolved oxygen sensors can be used to monitor the dissolved oxygen content in production water and finished products to ensure that product quality meets standards.
