KWS630 Aquaculture Fluorescence Dissolved Oxygen Sensor


KWS630 Aquaculture Fluorescence Dissolved Oxygen Sensor


The Kacise KWS630 fluorescence dissolved oxygen sensor is designed for the aquaculture industry. It has the characteristics of stable online monitoring, and it has excellent characteristics compared with the traditional type sensor. It has no membrane, no need electrolyte, strong anti-interference, no need for frequent calibration, no consumption of oxygen, no flow rate limitation, automatic temperature and Gas pressure compensation, fast reaction speed, long service life and more economical and convenient, so the fluorescence dissolved oxygen sensor is the best choice for real-time dynamic monitoring of oxygen content in aquaculture.


  • No membrane, no need electrolyte
  • No need to consume oxygen, not affected by flow rate
  • Built-in temperature sensor, automatic temperature compensation
  • Free from chemical interferences such as sulfides
  • Small annual drift, fast response, and more accurate measurement
  • Free of maintenance, longer application cycle and lower cost of use
  • Fluor cap replacement is simple
  • Support RS-485, MODBUS protocol
