GRAVITY: ****OG DISSOLVED OXYGEN SENSOR / METER KIT FOR ARDUINO

Product Details
SPECIAL INSTRUCTION:
Due to the International Import and Export Policy, the corrosive solution (acid & alkaline solution) is not allowed to deliver by air transportation. The filling solution is not included in the kit. You have to purchase it from local shop or deploy the solution by yourself, refer to WiKi FAQ-Q4. It can’t work without filling solution! Please be caution with the purchase!

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.
