摘要： The first branch 1a of the optical fiber 1 is connected to the light source 2, and the second branch 1b is connected to the optical measuring unit 3. A taper-shaped tip member 8 is fitted to a tip end of the optical fiber unit 1 with the use of a jig member 4. The inner hollow space 7 in the tip member 8 is connected with the air suction device 11, through the gap 5 formed between the optical fiber unit 1 and the jig member 4 and the air suction tube 10. The air suction device 11 discharges air from the inner hollow space 7 to suck liquid through the through-hole 6 into the inner hollow space. The air suction device 11 is controlled by the controller 12. Because the optical fiber unit can directly irradiate liquid with light, measurement can be performed with high sensitivity. The optical fiber unit is prevented from contamination.
