Liquid quality detector and liquid quality analysis system

摘要

To provide a liquid detector capable of suppressing an outer diameter of a peripheral portion between an electrical connector and a fluid connector.SOLUTION: The liquid detector 1 includes an outer peripheral wall 2 having a base end 2a and a tip 2b; a measuring electrode unit 3 formed on the inside of the outer peripheral wall 2 with a first internal electrode 3a; a comparison electrode 4 formed on the inside of the outer peripheral wall 2 with a second internal electrode 4a and a liquid entanglement 4b; an electrical connector 5 for electrical connection of both the first internal electrode 3 and the second internal electrode 4 to the external electrical connector 9 placed on a farther axial base end side than the outer peripheral wall 2; and a fluid connector 6 for fluid connection of the comparison electrode 4 to an external fluid connector 8a placed on the farther axial base end side than the outer peripheral wall 2, and the electrical connector 5 and the fluid connector 6 are arranged in series in the axial direction.SELECTED DRAWING: Figure 1
