Frequently Asked Questions (FAQ)
What makes the DO Sensor Type C suitable for aquaculture environments?
The DO Sensor Type C is specifically designed for harsh aquaculture conditions. Its fluorescent film features bacteriostasis, scratch resistance, and strong anti-interference capabilities, making it highly reliable in environments with high organic matter, algae blooms, or chemical treatments. The built-in temperature sensor also ensures automatic compensation for accurate readings.
How does fluorescence technology differ from traditional electrochemical DO measurement?
Unlike traditional electrochemical methods, fluorescence lifetime measurement does not consume oxygen during the sensing process and is not affected by flow rate variations. This results in more stable, precise dissolved oxygen readings with less interference, making it ideal for continuous online monitoring in dynamic water environments.
What is the accuracy and measurement range of the DO Sensor Type C?
The sensor offers an accuracy of ±0.3mg/L for dissolved oxygen and a temperature accuracy of less than 0.3℃. Its measurement range covers 0–20mg/L for dissolved oxygen and 0–50℃ for temperature, making it suitable for a wide variety of water monitoring applications.
Does the DO Sensor Type C require frequent maintenance or calibration?
No. One of the key advantages of this sensor is its low maintenance requirement. There is no need for electrolyte replacement or frequent recalibration, which significantly reduces operational costs and minimizes system downtime—especially beneficial for large-scale or remote aquaculture installations.
What communication protocol and power supply does the sensor support?
The DO Sensor Type C supports RS-485 communication with MODBUS protocol, enabling seamless integration with most existing water quality monitoring and control systems. It operates on a 9-24VDC power supply, with 12VDC recommended for optimal performance.
Can this sensor be used in applications other than aquaculture?
Yes. While it is optimized for aquaculture, the DO Sensor Type C is also well-suited for wastewater management (tracking oxygen in industrial or agricultural runoff with high particulate content) and environmental research (long-term monitoring in challenging natural water bodies such as estuaries or polluted lakes).
