Gravity: Analog Dissolved Oxygen Sensor/Meter Kit

Gravity: Analog Dissolved Oxygen Sensor / Meter Kit INTRODUCTION We launched a new opensource dissolved oxygen sensor kit, which is compatible with Arduino. This product is used to measure the dissolved oxygen in water, to reflect the water quality. This sensor kit helps you quickly to build your own dissolved oxygen detector. FEATURES Dissolved Oxygen Probe： 1. Galvanic probe, no need polarization time 2. Filling solution and membrane cap is replaceable, low maintenance cost Signal Converter Board: 1. 3.3~5.5V wide-range power supply, compatible with most Arduino microcontroller 2. 0~3.0V analog output, compatible with all microcontrollers with ADC function. 3. Gravity interface, plug and play, easy to use SPECIFICATION Dissolved Oxygen Probe Type: Galvanic Probe Detection Range: 0~20mg/L Response Time: Up to 98% full response, within 90 seconds (25℃) Pressure Range: 0~50PSI Electrode Service Life: 1 year (normal use) Maintenance Period: Membrane Cap Replacement Period: 1~2 months (in muddy water); 4~5 months (in clean water) Filling Solution Replacement Period: Once every month Cable Length: 2 meters Probe Connector: BNC Signal Converter Board Operating Voltage: 3.3~5.5V Output Signal: 0~3.0V Cable Connector: BNC Signal Connector: Gravity Analog Interface (PH2.0-3P) Dimension: 42mm * 32mm SHIPPING LIST Galvanic Dissolved Oxygen Probe with Membrane Cap x1 Spare Membrane Cap x1 Signal Converter Board x1 Gravity Analog Sensor Cable x1 Waterproof Gasket x2 Screw Cap for BNC Connector x1 Plastic Dropper x2

• This is a dissolved oxygen sensor kit, which is compatible with Arduino microcontrollers. 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.
• The 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.
• This 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.
• 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!
