I. Summary

The instrument is a mechanical rotational viscometer. It can measure the viscous resistance and dynamic viscosity of liquids in a wide viscosity range. It can be widely used to determine viscosity of oil grease, paint, plastics, food, medicine, adhesive, and other fluids.

II. Main technical characteristics

1. It adopts a synchronous motor, which rotates at a stable speed. The motor connects to the dial and it drives 
spindle rotating through hairspring and rotating shaft.

2. It uses gear system and clutch to change rotation speed. The rotation speed has four grades and it is controlled 
by a special knob. You can select a speed as per the test requirements.

3. The instrument is equipped with No.1 to 4 total 4 spindles, so you can select a suitable spindle and speed to meet 
different measurement requirements as per the viscosity of sample to be determined.

4. The instrument is equipped with a needle fixed device (needle control rod). When the rotation speed is high, 
it is convenient to read the reading using the needle control rod.
