The instrument has characteristics of high measurement sensitivity, reliable measurement data, convenience, and good looking. It can be used to determine absolute viscosity of Newtonian liquids and apparent viscosity of Non-Newtonian liquids. It has been widely used to determine viscosity of oil greases, paints, plastic materials, pharmaceuticals, coating materials, adhesives, washing solvents, and other fluids.


1. Adopting advanced mechanical design technology, manufacture technique and microcomputer controlling technology, it can collect data accurately. 

2. Using white background light and ultra-bright LCD, it can show test data clearly. 

3. 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 measurement.
