China Manufacturer Do probe Dissolved Oxygen Sensor for Water station
Compared with traditional polarographic electrodes, the fluorescence dissolved oxygen sensor developed and produced by Delfino is more suitable for real-time dissolved oxygen monitoring. Its shell is ABS sturdy and durable, the measurement results are accurate, and the maintenance is very easy. At the same time, it is also a digital electrode with built-in RS485 communication and supports Modbus protocol.

Features of the dissolved oxygen sensor
1. No need to calibrate, meet the requirements of on-site work
2. There is no need to consume oxygen, and it can be accurately
measured even when the oxygen concentration is low.
3. With RS458 interface, it supports access to standard industrial
control systems.
4. The protection grade is IP68, which can work continuously under
water for a long time.
5. Internal storage of calibration data, plug and play on site.
6. No need for polarization, no electrolyte. The service life is
1-2 years, and you can continue to use it after replacing the
fluorescent cap.
Application
It is widely used in urban sewage treatment, industrial wastewater
treatment, surface water monitoring, aquaculture and other
industries.
It can be matched with DUC2-DO single-parameter controller or
connected with MCC100 five-parameter controller to realize the
water quality monitoring of a set of water stations.
