Brookfield rotational viscometers

Brookfield rotational viscometers are designed and made as per industrial standard of People’s Republic of China T0625-2011 Rotational Viscosity Determination for Bitumen by Brookfield Viscometer in JTG E20-2011 Test Methods of Bitumen and Bituminous Mixtures for Highway Engineering. It is suitable to determine the absolute viscosity of Newtonian liquids and apparent viscosity of Non-Newtonian liquids.

The instrument has features of high sensitivity, reliable test result, easy operation and good looking structure.

The instrument adopts advanced mechanical design technology and manufacturing process, using micro- computer technology to control speed,collect data and process data.Equipped with high-light LCD screen and micro-needle printer.

The test data can show on the screen real time and also output by printer.In addition,the instrument can also connect with PC via RS232 communication port.
