ELECTRODE DEVICE FOR MEASUREMENT OF MINIATURE POTENTIAL IN LIQUID

摘要

PROBLEM TO BE SOLVED: To provide an electrode device for measurement of a miniature potential in liquid capable of withstanding dynamic movement in water. SOLUTION: The electrode device for measurement of a miniature potential in liquid includes a case 2 constituted by a cylindrical case body 3 and a lid 4. The cylindrical case body 3 is provided in the inside with an electrode 7 supported by a supporting body 5, a liquid chamber 8 around the electrode 7, a filter 14 disposed between the lid 4 and the liquid chamber 8. The filter 14 is made of a nonwoven fabric. The lid 4 is fastened with screws to the case body 3 so that the filter 14 is press-fixed through a press ring 15 on flanges 12 of the case body 3 through pressure rings. COPYRIGHT: (C)2010,JPO&INPIT
