20.00Mg/L Dissolved Oxygen Transmitter For Sewage Water Treatment

0.00~20.00 Mg/L Dissolved Oxygen Sensor For Sewage Water Treatment

Dissolved oxygen sensor OPD70 measurement methods include polarography and fluorescence. Polarography is cheap, but requires regular replacement of the diaphragm and electrolyte. The fluorescence method is expensive, but does not need to replace the diaphragm and electrolyte, and requires less maintenance. The measurement method used by our OPD70 dissolved oxygen sensor is the Fluorescence principle.

On-line dissolved oxygen analyzer with OPD70 dissolved oxygen sensor maintenance-free, dissolved oxygen electrode can continuously monitor dissolved oxygen in water, NTC automatic temperature compensation, panel type, wall-mounted type, pipe clamping installation method is optional, suitable for various weather and various used in complex industrial environments.
