6. The measuring electrode of claim 5, further comprising an upper seal, a side of the upper cover facing away from the flexible body being an adhesive surface, the upper seal being removably adhered to the adhesive surface and covering the connection aperture.

7. The measuring electrode of claim 6, further comprising a lower seal removably disposed on the contact surface and covering the drain hole.

8. The measurement electrode of claim 7, wherein the upper seal and the lower seal are release papers; and/or the upper seal and the lower seal are different in color.

9. The measurement electrode of any one of claims 1 to 8, wherein the flexible body is of annular configuration; and/or the flexible body is made of foam.

10. The measurement electrode of any one of claims 1 to 8, wherein the upper cover and the lower cover are of a thin film structure.

11. The measuring electrode according to any one of claims 1 to 8, wherein the upper cover and/or the lower cover is a transparent structure.

12. The measurement electrode of any one of claims 1 to 8, wherein the conductive medium is a conductive liquid or paste.

13. The measuring electrode according to any one of claims 1 to 8, wherein the thickness of the flexible body in the axial direction ranges from 3mm to 6mm.
