1. How is this different from traditional DO sensors?
2. How is it connected to the control system?
3. Is calibration required?
4. What should I do if I face any issues?
5. What is the operating temperature and pressure range?
It typically operates within 0–50°C and up to 5 bar pressure, making it suitable for most aquaculture and hydroponic environments.
6. Is the sensor affected by salinity or turbidity in water?
The fluorescence method is stable and minimally affected by salinity or turbidity, ensuring accurate readings in diverse water conditions.
7. Can it be used in continuous immersion applications (24/7 monitoring)?
Yes, it’s designed for continuous immersion and long-term 24/7 monitoring with low maintenance requirements.
