Stirring device for automatically measuring dissolved oxygen |
摘要 |
A rotor having N and S poles is rotatively supported through bearings from the lower end of an electrode to be immersed in a water sample in which dissolved oxygen is measured. A rotor driving means is disposed adjacent to the rotor, the means generally comprising a magnet which is so constructed that the N and S poles thereof alternately approach the rotor. The rotor follows the rotation of the rotor driving means to rotate in and stir the water sample.
