Torsional spring dynamometer is a special testing instrument designed to correct the stiffness and indication error of torsion spring in viscometer.

It is mainly composed of base, runner, fixed plate, column, crossbeam and etc.

The measuring accuracy of the rotational viscometer is directly related to the torsion spring and force measuring components of the instrument. Poor daily maintenance and management, corrosive gas erosion, all of them can cause the damage of torsion spring and force measuring components. In order to keep the instrument in better working condition, user should always correct it.

When use torsional spring dynamometer to measure, taking the measuring element- inner cylinder on the six –speed viscometer as the force transmission medium, the calibration method is simple and directly.
