PROBLEM TO BE SOLVED: To provide a method of measuring a dissolved substance, particularly a dissolved metal by an optical fiber.SOLUTION: An optical fiber 10 is supplied into a dissolved substance via a disposable guide tube 40. The optical fiber 10 and an immersed end portion 50 of the disposable guide tube 40 are immersed in the dissolved substance. Furthermore, the present invention relates to equipment and a device for measuring the dissolved substance, particularly a dissolved metal 52, and the equipment and the device each include the optical fiber 10 and the disposable guide tube 40. An elastic plug 30 is arranged on a second end portion of the disposable guide tube 40 or in the disposable guide tube 40. The optical fiber 10 is supplied via the elastic plug 30. The elastic plug 30 reduces a cavity between the optical fiber 10 and the disposable guide tube 40. The device comprises: a fiber coil; and a supply mechanism for supplying the optical fiber 10 and the disposable guide tube 40. The supply mechanism includes at least two independent supply motors, one for supplying the optical fiber 10 and the other for supplying the disposable guide tube 40. |
