The insulator is provided with a cylindrical first section, a cylindrical second section positioned on a rear end side of the first section and having an outer diameter F at the leading end thereof smaller than the outer diameter of the first section, a cylindrical third section positioned on a leading end side of the first section and having an outer diameter D at the rear end thereof smaller than the outer diameter of the first section and the outer diameter F of the leading end of the second section, a first inclined section connecting the first section and the second section and having an outer diameter decreasing toward the rear end side thereof, and a second inclined section connecting the first section and the third section and having an outer diameter decreasing toward the leading end side thereof. The axial length A of the second inclined section and axial length B of the first inclined section satisfy 2.0 ≤ A/B ≤ 3.9, and 0.50 ≤ D/F ≤ 0.88 is satisfied.
A water quality measuring system (100) is provided with: a first introducing portion (131) for introducing breeding water to be sampled; a first adding portion (132) for adding an acid to the breeding water that has been introduced by the first introducing portion (131); and a nitrous acid sensor (28) for measuring the concentration of a measurement target, where the measurement target is nitrous acid, contained in the breeding water after the acid has been added by the first adding portion (132). The water quality measuring system (100) is provided with: a second adding portion (133) for adding a base to the breeding water that has been introduced by the first introducing portion (131); and an ammonia sensor (26) for measuring the concentration of a measurement target, where the measurement target is ammonia, contained in the breeding water after the base has been added by the second adding portion (133).
