摘要：A concentration measuring apparatus includes a vibration member; a shieldingunit that limits a flowable area of a solution to be measured close to the vibrationmember; a vibration control unit that vibrates the vibration member at a frequency; avariation measuring unit that measures a physical variation of the vibration member
vibrated; an eigenfrequency computing unit that computes an eigenfrequency of thevibration member in the solution from the frequency and the variation; and aconcentration obtaining unit that obtains a concentration of the solution from theeigenfrequency and a correspondence between the eigenfrequency and theconcentration of the solution.
