DOG-209FA Industrial Dissolved Oxygen Electrode
Features
DOG-209FA type oxygen electrode improved from the previously dissolved oxygen electrode,
Change diaphragm into a grit mesh metal membrane, with high stability and stress resistant,
Can be used in a more harsh environment, maintenance volume is smaller, suitable for urban
Sewage treatment, industrial wastewater treatment, aquaculture and environmental monitoring
And other fields of continuous measurement of dissolved oxygen.
Which have the USB connector, can connect with the computer / PLC directly by the RS485.
