Gas sensitive electrodes-Oxygen
Oxygen-electrode
For the determination of dissolved oxygen according to the Clark-principle and carbon dioxid according to the Severinghouse-principle in water irrespective of colour or turbidity.
The oxygen-electrode with an integrated temperature sensor measures the dissolved oxygen in water and operates on the principle of CLARK. The electrode is a platinum electrode provided with a O2-permeable membrane. Between the platinum electrode and the reference electrode (Ag/AgCl) a constant polarization voltage is applied. Because of the diffusion of O2 through the membrane a current is measured which is proportional to oxygen concentration.
Applications
