ELECTRODE DEVICE FOR UNDERWATER POTENTIAL MEASUREMENT, AND UNDERWATER POTENTIAL MEASUREMENT DEVICE

摘要

PROBLEM TO BE SOLVED: To provide an electrode device for underwater potential measurement with which it is possible to accurately calculate an underwater potential difference in a reference electrical resistivity or electrical conductivity without separately installing a device for measuring electrical resistivity or electrical conductivity.;SOLUTION: An electrode device 1 for underwater potential measurement comprises an electrode 12, an enclosure 11 for covering the electrode 12 and having an opening 111 that communicates with the outside, and a cylindrical member 13 connected to the enclosure 11 and having a space 131 that communicates with the opening 111 of the enclosure 11. The electrode device 1 for underwater potential measurement is configured to be able to measure a potential difference between outside waters, and to measure the electrical resistivity or electrical conductivity of outside water flowing into the cylindrical member 13 turning power to the electrode 12 on.;SELECTED DRAWING: Figure 2;COPYRIGHT: (C)2016,JPO&INPIT
