Using a coaxial center structure, using a small sample adapter, each measurement requires a very small sample size, temperature control quickly and accurately. It has many measuring parameters, rich display content, convenient operation, intuitive reading, high measuring precision, stable rotational speed, strong anti-interference performance, wide working voltage and so on. can replace the same type of imported instrument.
Main features:
- 1. adopts ARM technology, built-in Linux system. Operation interface is simple and clear, through the creation of testing procedures and data analysis, fast and convenient viscosity testing;；
- Accurate viscosity measurement: each measuring range is automatically calibrated by computer with high precision and small error；
- Display rich: in addition to viscosity (dynamic viscosity and kinematic viscosity), there are temperature, shear rate, shear stress, measured value as a percentage of the full range value (graphic display), range overflow alarm, automatic scanning, maximum measurement range under the current rotor speed combination, date, time, etc. The kinematic viscosity can be displayed under the known density to meet the different measurement requirements of users；
- Fully functional: can be timed measurement, self-built 30 groups of testing procedures, access to 30 groups of measurement data, real-time display viscosity Curves, printed data, curves, etc.；
- Stepless speed regulation:
RV1T series:0.3-100 rpm, a total of 998 rotational speeds
RV2T Series:0.1-200 rpm,2000 rpm
- Shows the curve of shear rate to viscosity: can set the range of shear rate, real-time display on the computer; can also show the curve of time to viscosity
- Operating System in English and Chinese
Measurable in a very large range from 50 to 80 million MPA.S, samples that can meet various high viscosity high temperature melts (e.g. hot melt adhesive, asphalt, plastics, etc.)
Optional ultra-low viscosity adapter (rotor 0) can also measure the viscosity of paraffin wax, polyethylene wax if molten sample.
