Analog Dissolved Oxygen Sensor Meter Kit (DFRobot Gravity) - SEN0237-A

This is a dissolved oxygen sensor kit used to measure the amount of dissolved oxygen in water — a key indicator of water quality. It's ideal for applications such as aquaculture, environmental monitoring, and scientific research. Low dissolved oxygen levels can pose a threat to aquatic life, making this sensor essential for maintaining healthy water environments.

The included galvanic probe requires no polarization time and is always ready to use. Both the membrane cap and filling solution are replaceable, ensuring low maintenance costs. The signal converter board is plug-and-play and supports a wide voltage range (3.3V–5.5V), making it compatible with most microcontrollers like Arduino.

Note:

  • The filling solution (0.5 mol/L NaOH) is not included due to international shipping restrictions. It must be prepared or purchased locally.
  • Always wear gloves when handling the solution, as it is corrosive. In case of contact with skin, rinse with water immediately.
  • Handle the membrane cap with care; it is fragile and sensitive to damage.
  • Stir the water gently during measurement to evenly distribute the oxygen.
