Analog Dissolved Oxygen Sensor / DO Meter Kit For Arduino

THE FILLING SOLUTION (NaOH) IS NOT INCLUDED IN THE KIT

Note:
1. The filling solution is 0.5 mol/L NaOH solution. You need to pour it in the membrane cap before use. Please be caution with the operation because the solution is corrosive. Please wear gloves! If the solution accidentally drops onto the skin, wash your skin with plenty of water immediately.
2. The oxygen permeable membrane in the membrane cap is sensitive and fragile. Be caution when handling with it. Fingernail and other sharp objects should be avoided.
3. The DO sensor will consume a little oxygen during the measurement. Please gently stir the solution and let the oxygen to be distributed evenly in the water.

FEATURES
