| Detailed Description | The sensor is a galvanic cell type dissolved oxygen water quality sensor. Oxygen molecules in the test solution pass through the selective membrane of the sensor and undergo corresponding reduction or oxidation reactions at the cathode and anode inside the sensor, generating a current signal. The magnitude of the current is proportional to the dissolved oxygen concentration, and the concentration of dissolved oxygen is determined by the magnitude of the current. |
| Main Applications | Dissolved oxygen water quality testing is widely used in laboratory research, aquaculture, environmental protection and other fields. |

| Instructions For Use | 1. Prepare 9 mg/L and 0 mg/L standard solutions for calibration. See the product instruction card for preparation instructions. 2. Connect the sensor interface to the corresponding location on the module or instrument. 3. Remove the protective cover from the sensor test end and calibrate it sequentially in the 9 mg/L and 0 mg/L standard solutions. 4. After calibration, immerse the sensor test end in the test solution for testing. 5. Clean the sensor test end promptly after use and replace the protective cover. Store at room temperature. |
