Title:
COMPOSITE ELECTRODE BOTH FOR SUCTION AND CIRCULATION MEASUREMENTS
Document Type and Number:
Japanese Patent JP3808952
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide an inexpensive composite electrode which can easily perform both circulation measurement and suction measurement.
SOLUTION: A double tube 4 comprising an inner tube 1 forming a flow path of sample liquid and an outer tube 2 branched from the middle of the inner tube 1 for surrounding the inner tube 1 so that a ring-like space 3 is formed between the inner tube 1 and it is integrally formed of glass, a response film 5 is formed on a part of the inner tube 1 surrounded by the outer tube 2, the space 3 between the inner tube 1 and the outer tube 2 is filled with glass electrode internal liquid 6, and an inner electrode 7 is provided at a position corresponding to the response film 5 in the glass electrode internal liquid 6. On the other hand, the double tube 4 is surrounded by an outer cylinder 8 so that a ring-like gap 9 is formed between the double tube 4 and it, the gap 9 is filled with reference electrode internal liquid 10, a liquid junction 11 is provided on a part of the inner tube 1 in contact with the reference electrode internal liquid 10, and a reference electrode inner pole 12 is provided in the reference electrode internal liquid 10 corresponding to the liquid junction 11.
