LVDV-2 Rotary Viscometer

main features:

1.Scosity measurement accuracy:each range is automatically calibrated by a computer,with high accuracy and small error;

2.Front-level instrument:the level adjustment is intuitive and convenient;

3.Optional Pt100 temperature probe:wide temperature measurement range,from-20 to 300℃,temperature measurement accuracy of 0.1℃;

4.Optional enhanced ultra-low viscosity adapter ULR/URL PLUS,which can accurately measure the viscosity of 1mPa.S;

5.Select a small amount of sample adapter,SSR/SSR PLUS,and the sample volume measured each time is only 7-11ml;

6.Rich optional accessories:constant temperature bath,constant temperature cup,printer,standard viscosity sample(standard silicone oil),etc.;

7.With automatic scanning,timing measurement and other functions;

8.Automatic prompt function of viscosity measurement and stability;

9.Showing the shear rate and the shear stress;

10.Sviscosity unit switching(1Pa.s=1000mPa.s;1P=100mPa.s;1cP=1mPa.s);

11.Temperature unit switch:Celsius,F;

12.Connect to the printer and the computer

13.Switching between Chinese and English operating systems

The torque of the gossamer,the shape of the rotor,the size of the rotation speed,and the range of the

viscosity measurement are the same as the same viscometer imported,and the measured viscosity data is very

well comparable with the imported similar instruments.Widely used in paint,paint,cosmetics,ink,pulp,food,oil products,starch,adhesives,latex,biochemical products and other industries.It can also be optional high temperature furnace measurement need heating melt samples such as asphalt,hot melt glue,polyethylene wax and other samples.
