It can be used as a stand-alone machine, or it can be connected to a micro-printer and a computer to realize data collection.
High subdivision drives the stepper motor to rotate, the speed is accurate and stable, and the frequency change of AC Voltage does not affect the accuracy of viscosity measurement.
For thixotropic non-Newtonian liquids, the timing function of the instrument can ensure good consistency data.
With humanized, personalized design, 2000 kinds of shear rate stepless setting. It can simultaneously display shear stress, shear rate, rotational speed, viscosity, time, temperature and the maximum viscosity value that the rotor can measure at the current rotational speed.
DVLoad software can be purchased to download the custom measurement program to the instrument to realize full computer automatic operation, and DV data acquisition and program-controlled analysis software can also be purchased to realize data acquisition and program-controlled analysis.
The full scale and linearity of LDV-2+Pro digital viscometer are all measured and corrected through the PC interface, and its measurement performance and functions have reached the professional level of the same type abroad.
The built-in RTD temperature probe monitors the sample temperature in real time, with an accuracy of 0.1°C and a temperature range of 0-100°C.
Different standard rotors can be selected according to needs
Using 16-bit microcomputer processor as the core stepping motor high subdivision drive, digital LCD with blue backlight function.
According to the need, you can choose the standard material of the Metrology Bureau to calibrate the viscometer, so that the inspection level can be in line with the international standard.

Small sample adapter (with 21#, 27#, 28#, 29# rotor
If a small sample adapter is selected, the measuring range will be reduced by 6 times under the corresponding specification)
