MW-O101 Dissolved Oxygen Sensor
The MW-O101 sensor is a primary battery type dissolved oxygen water quality detection sensor. The oxygen molecules in the solution to be tested pass through the selective membrane of the sensor, and the corresponding reduction or oxidation reaction occurs on the cathode and anode inside the sensor, and a current signal is generated at the same time. The current is proportional to the dissolved oxygen concentration. oxygen concentration.

Instructions
Prepare 9 mg/L and 0 mg/L standard solutions for calibration. For the preparation method, please refer to the product use reminder card.
Connect the sensor interface end to the corresponding position on the module or instrument.
Remove the protective cover of the test end of the sensor and place it in the standard solution of 9 mg/L and 0 mg/L in turn for calibration.
After the calibration is completed, place the test end of the sensor in the liquid to be tested for testing.
Clean the sensor test end in time after use, and install the protective cover. Store at room temperature.
