Data Harvest Wireless Dissolved Oxygen Sensor 1114

Data Harvest have developed a unique concept, simply click the smart button 3 times and the Smart Sensor will instantly start recording your data. From out of the box you can begin your science activities and share your results with the class. Furthermore you can instantly stream the data using the new EasySense2 software in real time! Furthermore the range of Sensors come with a huge battery life to ensure your experiments are not interrupted! The Oxygen sensor uses an electrode of the Polarographic (Clark cell) type. This electrode is used in combination with the Oxygen Adaptor to form the dissolved oxygen sensor for measuring oxygen levels in water. The anode and cathode are immersed in electrolyte and separated from the sample by a semi-permeable membrane. The oxygen permeability of the membrane is temperature dependent. This variation in permeability is automatically compensated by a temperature compensation thermistor over the 5 to 45°C operating range.
