►Typical applications:
It can be extensively used in the monitoring of dissolved oxygen in the fields such as waterworks, surface water and aquaculture.
Sewage treatment process
Monitoring and control of water quality in aquaculture
Monitoring and control of water quality in aquaculture
Measurement of oxygen content in drinking water and surface water
Monitoring of dissolved oxygen in food and beverage production
►Instrumentions for Ordering:
When purchasing,please inform the field or industry of use and the characteristics of the measuring medium in order to provide appropriate technical service guidance.
Standard supplies of dissolved oxygen analyzer are as follows:
Controller, Sensor, Mounting accessories
►Optical Dissolved Oxygen Sensor:
Optical dissolved oxygen sensor could provide reliable dissolved oxygen measurement over a long service life without replacing the membrane, refilling the ellectrolyte solution or cleaning the anode. For maintenance of the sensor, only the fluorescent cap is replaced every 1-2 years. Since all calibration data is stored on the cap, calibration is not required. The dissolved oxygen sensor outputs Modbus/RS485 digital signal to facilitate the PCL integration.
►Menbrane Dissolved Oxygen Sensor:
Membrane dissolved oxygen sensor applies the electrochemisty measuring principles to measure the oxygen content in water. With the advantages such as fast response time, accurate measuring results and simple calibration, only single-point air calibration is required, and its large electlyte reservoir reduces downtime due to maintenance. The dissolved oxygen sensor directly outputs4-20mA analog signal or Modbus/RS485 digital signal to facilitate the PLC integration.
Principle of typical primary cell
