Description
LVDV-1T/2T Touch Screen Viscometer
Main features:
Using ARM technology, built-in Linux system. The operation interface is simple and clear, and the viscosity test is carried out quickly and conveniently through the creation of test program and data analysis;
The viscosity measurement value is accurate: each measuring range uses the computer automatic calibration, the precision is high, the error is small;
2 Rich display: in addition to viscosity (dynamic viscosity and kinematic viscosity), there are temperature, shear rate, shear stress, measured value as a percentage of full range value (graphic display), range overflow alarm, automatic scanning, the measurement range under current rotor speed combination, date, time, etc. The kinematic viscosity can be displayed in the case of known density to meet the different measurement requirements of users;
4 Complete function: can measure time, self-built 30 sets of test program, access 30 sets of measurement data, real-time display viscosity curve, print data and curve;
5 Front level instrument: level adjustment is intuitive and convenient;
6 stepless speed regulation: RV1T series :0.3-100 rpm ,998 rpm
RV2T series :0.1-200 rpm ,2000 rpm
Show the curve of shear rate to viscosity: can set the range of shear rate, real-time display on the computer; can also
A curve showing time versus viscosity
Standard USB interface: insert U disk to copy data directly
Optional Pt100 temperature probe: temperature range from -20 to 300℃, temperature measurement accuracy 0.1℃;
10 Rich optional accessories: Viscometer dedicated thermostatic bath, thermostat cup, printer, standard viscosity sample (standard silicone oil)
etc;
- Chinese and English operating system (set before leaving the factory).
the torque of the filament, the shape of the rotor, the size of the rotational speed, and the range of viscosity measurement are the same as the imported viscometer of the same type. the measured viscosity and other data are well comparable with the imported similar instruments.
Widely used in paint, paint, cosmetics, ink, pulp, food, oil, starch, solvent adhesive, latex, biochemical products and other industries.
