Data Harvest

Product Description


This sensor utilises a specialised electrode, known as a Polarographic (Clark cell) electrode, along with the Oxygen Adaptor, to provide accurate and reliable readings of dissolved oxygen levels.

With this sensor, you can effortlessly monitor the oxygen content in water without any hassle.

The electrode, consisting of an anode and cathode, is immersed in an electrolyte and shielded from the water sample by a convenient semi-permeable membrane. This membrane allows oxygen to pass through, while the temperature-dependent permeability is automatically adjusted over a broad operating range of 5 to 45°C using a built-in temperature compensation thermistor.

Our Oxygen sensor is a game-changer, making oxygen level measurements in water easier and more accessible than ever before.


Bluetooth | USB | Huge Battery Life | Independent Logging




Here are just a few example practical ideas you can achieve by using the Wireless Oxygen Dissolved Sensor. 

  • On-site testing in streams & ponds
  • Lake survey to evaluate the capability of the water to support different types of plant and animal life
  • Change in oxygen levels around an aquatic plant
  • Part of data for water quality
  • Fish tank / aquaria water quality
  • Cellular respiration of yeast cells / suspension
