DISSOLVED OXYGEN MEASUREMENT SYSTEM AND METHOD FOR CALIBRATING DISSOLVED OXYGEN METER |
摘要 |
In order to improve measurement accuracy by calibrating the sensitivity of a dissolved oxygen meter with good precision without compromising simplicity during calibration, the present invention is provided with: a dissolved oxygen measurement device (101) provided with a cell (20) into which a sample liquid is introduced, and a dissolved oxygen meter (30) for measuring oxygen concentration in a sample liquid, the dissolved oxygen meter (30) being mounted to the cell (20); and a mode switching mechanism (102) for switching between a measurement mode in which a sensor surface (32) of the dissolved oxygen meter (30) essentially makes contact with the sample liquid in the cell (20), and a calibration mode in which the sensor surface (32) is essentially brought into no contact with the sample liquid inside the (20) by discharging a portion of the sample liquid from a discharge port (24) provided to the cell (20). |
