This product 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 and so on. Dissolved oxygen is one of the important parameters to reflect the water quality. Low dissolved oxygen in water will lead to difficulty in breathing for aquatic organisms, which may threaten their lives. \u003c\/p\u003e\n\u003cp\u003eThe probe is a galvanic probe, no need of polarization time, and stay available at any time. The filling solution and membrane cap is replaceable, leading to the low maintenance cost. The signal converter board is plug and play, and has the good compatibility. It can be easily integrated to any control or detecting system.\u003cbr\u003eThis product is easy to use with high compatibility. With open-source code and detailed tutorial provided, this product is very suitable for your water projects in detecting the dissolved oxygen concentration for the aquatic organisms.\u003c\/p\u003e\n\u003cdiv\u003e\n\u003cimg alt=\"Arduino Dissolved Oxygen (DO) Sensor Connection Diagram\" src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0531\/3419\/6927\/files\/SEN0237-Connection_20Diagram.jpg\" title=\"Arduino Dissolved Oxygen (DO) Sensor Connection Diagram\"\u003e\u003cbr\u003eArduino Dissolved Oxygen (DO) Sensor Connection Diagram\u003c\/div\u003e\n\u003cp\u003e\u003cspan style=\"color: #ffffff;\"\u003eSPECIAL INSTRUCTION:\u003c\/span\u003e\u003cbr\u003e\u003cspan style=\"color: #ff0000;\"\u003eDue to the International Import and Export Policy, the corrosive solution (acid \u0026amp; alkaline solution) is not allowed to deliver by air transportation.
