Ndj-1b Laboratory Equipment Rotational Viscometer

I. Summary
The instrument adopts advanced mechanical design technology, manufacture technique
and microcomputer controlling technology.It can collect data accurately. Using white background light and ultra-bright LCD, it can show test data clearly. Equipped with a special printer interface, it can print out measurement data through a printer.
The instrument has the characteristics of high sensitivity, reliability, convenience and good looking. It is used to determine absolute viscosity of Newton liquids and apparent viscosity of Non-Newton liquids. It is widely used to determine the viscosity of liquids such as greases, oil paints, plastics, pharmaceutics, coatings, adhesives, washing solvents, and other fluids.
