| Detailed Description | The sensor is a polarographic dissolved oxygen sensor. Under a certain polarization potential, dissolved oxygen in the water permeates through an oxygen-permeable membrane and undergoes an oxidation-reduction reaction on the surface of the working electrode. The resulting current is proportional to the concentration of dissolved oxygen in the water. The concentration of dissolved oxygen in the water is calculated by measuring the magnitude of the current. |
| Main Applications | Dissolved oxygen water quality testing is widely used in laboratory research, aquaculture, environmental protection and other fields. |
