For measurement of oxygen concentration in air or soil
This sensor measures the amount (%) of Oxygen gas in air and is suitable for soil and laboratory studies.
They are galvanic cell type sensors with a lead anode, a gold cathode, an acid electrolyte and a Teflon membrane. The current flow between the electrodes is proportional to the oxygen concentration being measured. An internal bridge resistor is used to provide a mV output.
