The comparison of calibration for Stormer viscosimeter;

A detailed analysis on the principle of coaxial cylinder rational viscometer;

According to the requirements of application and maintenance,the main points and experiences of TOV viscometer that the field suits well in calibration and maintenance are introduced.

Analysis and amelioration of viscosimeter;

By analyzing the principle of two viscosimeters commonly used in physics experimental teaching,this article proposed that both of them have the system errors from measurement principle,and introduced a measuring equipment to eliminate the above system errors.
