Asphalt Brookfield Rotational Viscometer Viscosity Test Apparatus by ASTM D 4402
Summary
The brookfield viscometer is designed and made as per T 0625-2011 “Asphalt Brookfield Rotational Viscosity Test (Brookfield Viscometer Method)” in the Industry Standard of People’s Republic of China JTG E20-2011 Specification and Test Methods of Bitumen and Bituminous Mixture for Highway Engineering. It is suitable to determine absolute viscosity of Newtonian liquids and apparent viscosity of Non-Newtonian liquids. It can be widely used to determine viscosity of asphalt, hot melt adhesive, paraffin, high polymer, and various fluids.
I. Main technical features
1. The rotational brookfield viscometer adopts advanced mechanical design technology and manufacturing process, using micro-computer technology to control speed, collect data and process data. Accurate data acquisition, high sensitivity, reliable test results, easy to use, and good looking.
2. Display selection of white backlight, high brightness LCD display, can directly display the viscosity of the sample, the number of the rotor, speed and other information, data display clear.
3. The test data can show on the screen real time and also output by printer. In addition, the brookfield viscometer can also connect with PC via RS232 communication port.
4. Choose different models can have different ranges, for measuring different samples.
