Frequently Asked Questions (FAQ)
What makes the DO Sensor Type C specifically suitable for aquaculture environments?
The DO Sensor Type C is specially designed for harsh aquaculture conditions. Its fluorescent film features bacteriostasis, scratch resistance, and strong anti-interference ability, making it reliable in polluted, high-biomass, or chemically treated water bodies such as fish ponds, shrimp hatcheries, and recirculating aquaculture systems (RAS).
How does fluorescence technology improve dissolved oxygen measurement accuracy?
Unlike traditional electrochemical methods, fluorescence lifetime measurement does not consume oxygen during the sensing process and is not affected by water flow rate. This results in more stable and precise dissolved oxygen readings (±0.3mg/L accuracy), even in challenging or turbulent water conditions.
Does the DO Sensor Type C require frequent maintenance or calibration?
No. One of the key advantages of this sensor is its low maintenance design. It eliminates the need for electrolyte replacement or frequent recalibration, significantly reducing operational costs and minimizing downtime in continuous monitoring applications.
What communication protocol does the DO Sensor Type C support, and how can it be integrated into existing systems?
The sensor supports RS-485 communication with MODBUS protocol, which is widely used in industrial monitoring systems. It is compatible with 9-24VDC power supplies, making it easy to integrate into existing water quality monitoring networks, SCADA systems, or data loggers without major infrastructure changes.
What is the measurement range and operating temperature of the DO Sensor Type C?
The sensor measures dissolved oxygen in the range of 0–20 mg/L and temperature from 0–50℃. It operates reliably within an ambient working temperature of 0–40℃ and can be stored at temperatures between -5℃ and 70℃. A built-in temperature sensor provides automatic temperature compensation for accurate readings.
Can this sensor be used for applications beyond aquaculture, such as wastewater or environmental monitoring?
Yes. While the DO Sensor Type C is optimized for aquaculture, it is also well-suited for wastewater management—tracking oxygen levels in industrial or agricultural runoff with high particulate content—as well as long-term environmental research in challenging natural water bodies such as estuaries, polluted lakes, and rivers.
