Online Fluorescence Dissolved Oxygen Digital Sensor for Sewage Treatment
Fluorescence online dissolved oxygen sensor has high sensitivity, wide measurement range, real-time monitoring ability, easy to use, no need for sample treatment, and has the advantages of high accuracy, long life and stability, so it is widely used in many application fields application.
High sensitivity: The fluorescence method online dissolved oxygen sensor is very sensitive to the detection of oxygen. It is capable of accurate measurements at very low oxygen concentrations, providing highly sensitive dissolved oxygen measurements.
Wide measurement range: Fluorescence online dissolved oxygen sensor can measure in a wide range of dissolved oxygen concentration, from several nanomolar to saturated dissolved oxygen concentration can be accurately measured.
Real-time monitoring: Fluorescence online dissolved oxygen sensor can monitor the changes of dissolved oxygen in real time and provide instant measurement results. This is useful for applications that require timely response and adjustment, such as water quality monitoring, water treatment, biological processes, etc.
No need for sample processing: Compared with other sensor technologies, the fluorescence online dissolved oxygen sensor does not require complex sample processing or adding reagents, making the measurement process easier and more efficient.
High accuracy: Due to the high sensitivity and stability of the fluorescence online dissolved oxygen sensor, it can provide highly accurate dissolved oxygen measurement results. This is important for applications that require accurate monitoring and control of dissolved oxygen levels, such as water quality monitoring, water treatment, biological processes, etc.
Long life and stability: Fluorescence online dissolved oxygen sensors usually have a long service life and good stability to changes in environmental conditions. This makes it very reliable for long-term monitoring and continuous operation applications.
