PROBLEM TO BE SOLVED: To correct a measuring error against a temperature change due to various factors and accurately measure. SOLUTION: A viscometer is provided with a responsive plate 18 immersed into a measured object, an electromagnetic driver 23 for electromagnetically vibrating the responsive plate 18 in the measured object, a current detector 44 for measuring a drive current supplied to the electromagnetic driver 23, a drive mechanism 12 for supporting the responsive plate 18 and having the electromagnetic driver 23, a temperature sensor 28 for measuring a temperature of the drive mechanism 12, a displacement sensor 24 for detecting a vibration of the responsive plate 18 and a calculation processor for finding viscosity of the measured object based on the drive current when the responsive plate 18 is vibrated and has predetermined amplitude. The calculation processor corrects the measured viscosity on the basis of the detected temperature from the temperature sensor 28. COPYRIGHT: (C)2005,JPO&NCIPI
