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 bacteriostatic properties, scratch resistance, and strong anti-interference capability, making it highly durable in water bodies with high organic matter, algae, 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 sensors, fluorescence-based measurement uses fluorescence lifetime detection, which does not consume oxygen during measurement and is not affected by flow rate. This results in more stable, accurate, and long-lasting performance with minimal maintenance requirements.
What communication protocol does the DO Sensor Type C support?
The sensor supports RS-485 communication with MODBUS protocol, making it easy to integrate with a wide range of existing water quality monitoring systems, PLCs, and data loggers. It is compatible with power supplies ranging from 9 to 24VDC.
How often does the DO Sensor Type C require calibration or maintenance?
One of the key advantages of this sensor is its low maintenance design. It does not require electrolyte replacement or frequent calibration, significantly reducing operational costs and system downtime compared to traditional polarographic or galvanic sensors.
Can this sensor be used for applications other than aquaculture?
Yes. While 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 applications such as monitoring estuaries, polluted lakes, or other challenging natural water bodies.
What is the measurement range and accuracy 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 offers an accuracy of ±0.3 mg/L for dissolved oxygen and less than 0.3℃ for temperature, with a response time greater than 120 seconds for stable and reliable readings.
