MEASUREMENT DEVICE

摘要

A measurement device (1) has a measurement container (13) filled with liquid (12) and also has a sensor (11) placed in the measurement container (13) and detecting components of a gas sample dissolved in the liquid (12). The measurement device (1) further has a bubble generation section (14) to which the gas sample is supplied and having a hole (141) for discharging the gas sample into the liquid in the form of gas bubbles. In the bubble generation section (14), the hole (141) is provided so as to face the sensor (11) and be spaced with a predetermined distance from the sensor (11). If the distance between the bubble generation section (14) and the sensor (11) is X and the diameter of the hole (141) of the bubble generation section (14) is Y, 1/2Y = X = 3/2Y is satisfied.
