1. Instrument Overview: This instrument is a mechanical pointer rotary viscometer, which can measure the viscosity resistance of liquids and the dynamic viscosity of liquids within a large range. It can be widely used in the measurement of various fluid viscosity such as grease, paint, plastics, food, drugs, adhesives, etc.

2. Main technical characteristics
1. A synchronous motor is used to rotate at a stable speed, connect the scale disc, and then drive the rotor to rotate through the hairspring and the shaft.
2. The gear system and clutch are used for speed change, operated by a special rotating knob, and the speed is divided into four speeds, which can be selected according to the measurement needs.
3. There are four types of rotors 1 to 4, which can be used in conjunction with the speed according to the viscosity of the measured liquid.
4. It is equipped with a pointer fixed control device (pointer control lever) to facilitate accurate readings when the speed is fast.
