GDJ-8S Digital Rotational Viscometer

The instrument has the characteristics of high sensitivity and reliability, convenient to use and good looking. It is used to determine absolute viscosity of Newtonian fluids and apparent viscosity of Non-Newtonian fluids. It can be widely used to determine the viscosity of liquids such as greases, oil paints, plastics, pharmaceutics, coatings, adhesives, washing solvents, and other fluids.

GDJ-8S Digital Rotational Viscometer


The  instrument adopts advanced mechanical design technologies, manufacturing  techniques, and microcomputer controlling techniques, so it can collect data  accurately. It uses background light, ultra-brighten LCD, so it can show test  data clearly. It has a special printing port, so it can print out test data  through a printer.

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.
