FLOW CELL FOR LIQUID SENSOR SUCH AS DISSOLVED OXYGEN SENSOR AND WATER QUALITY ANALYZER

摘要

PROBLEM TO BE SOLVED: To reduce flow rate influence in a liquid sensor by increasing the flow rate of a liquid as a measuring object supplied by a DO (dissolved oxygen) sensor to increase the replacement speed of the liquid as a measuring object in the vicinity of a sensor surface of the DO sensor. SOLUTION: This flow cell 3 for the DO sensor supplies a liquid as a measuring object to the DO sensor. The flow cell includes: a flow cell body 31 housing the DO sensor and having a supply port P1 for supplying the liquid as a measuring object to the interior thereof; and a throttling structure provided on the flow cell body 31 to form an opening opposite to the DO sensor and communicated with the supply port P1.
