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.
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.
Yuyang series digital viscometer is the instrument that has been
adopt the most advanced newest mirco-computer drive
technology,imported stepping motor,and LCD displaying.It has the
function of stable rotate speed,high accuracy,easy operation,error
alarm and automatic scanning;It can provide the best combination
for rotor and rotate speed;Automatically displaying the maximum
measuring range for the combination chosen;Screen can directly
display the following data:viscosity,rotate speed,percentage
torque,rotor model and temperature for the testing objects.
Yuyang series digital viscometer can measure the absolute viscosity
for newtonian liquids and apparent viscosity for non-newtonian
liquids.If choose viscometer data processing software,can analyze
the simple rheological property for non-newtonian liquids.
Application
Grease,paint,coating,sizing agent,spinning,food,medicine,cementing
compound,cosmetic.,etc.
