Using synchronous motor with stable rotational speed, connecting scale disc and then through the gossamer and shaft drives the rotor to rotate.
Using gear and clutch system to variable speed, operated by a dedicated rotary knob, divided into four stalls
speed, can be selected based on the measurement.
With 1 to 4 four kinds of rotors, can be preset 4 stall speed, according to the measurement of the viscosity of the liquid to choose the speed with the use of speed, meet the requirements of different range of measure-ment.
Equipped with a fixed control device (pointer control lever), easy to read accurate readings when speed faster.
