Description
This is a dissolved oxygen sensor kit. A dissolved oxygen meter is used to measure the dissolved oxygen in water, to reflect the water quality. It is widely applied in many water quality applications, such as aquaculture, environment monitoring, natural science, etc.
There’s an old saying regarding keeping fish, “Good fish deserves good water”. Good water quality is very important to aquatic organisms. Dissolved oxygen is one of the important parameters to reflect water quality. Low dissolved oxygen in the water will lead to difficulty in breathing for aquatic organisms, which may threaten their lives.
The probe is galvanic, does not need polarization time, and stays available at any time. The filling solution and membrane cap are replaceable, leading to the low maintenance cost. The signal converter board is plug-and-play and works from 3.3V - 5V which makes it compatible with most popular microcontrollers.

SPECIAL INSTRUCTION:
Due to the International Import and Export Policy, the corrosive solution (acid & alkaline solution) cannot be delivered by air transportation. The filling solution is not included in the kit. You have to purchase it from the local shop or deploy the solution by yourself, refer to WiKi FAQ-Q4. It can’t work without a filling solution! Please be cautious with the purchase!
Note:
1. The filling solution is 0.5 mol/L NaOH solution. You need to pour it into the membrane cap before use. Please be cautious 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 cautious when handling 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 be distributed evenly in the water.
