Introduction: The stepless speed regulation LVDV / RVDV / HADV / HBDV series viscometers can measure a very large range, from 1 to 320 million mPa.S, covering almost most of the samples. The performance is similar to the imported viscometers of the same type and can be used instead. The torque of the hairspring, the shape of the rotor, the size of the rotational speed, and the range of viscosity measurement are the same as those of the imported viscometers of the same type. The measured viscosity and other data are well comparable to the imported similar instruments. Widely used in paints, coatings, cosmetics, inks, pulp, food, oil, starch, solvent-based adhesives, latex, biochemical products and other industries and samples that need to be heated and melted such as paraffin, polyethylene wax, rosin, asphalt, heat Melt glue, etc. Features: 1, using ARM technology, built-in Linux system. The operation interface is concise and clear, through the creation of test programs and data analysis, the viscosity test can be carried out quickly and conveniently; 2. Accurate viscosity measurement: each range is automatically calibrated by computer, with high precision and small error; 3. Rich display content: in addition to viscosity (dynamic viscosity and kinematic viscosity), there are temperature, shear rate, shear stress, measured value as a percentage of full scale value (graphical display), range overflow alarm, automatic scan, current rotor Viscosity measurement range, date, time, etc. under the combination of rotational speed. It can display kinematic viscosity under the condition of known density to meet the different measurement requirements of users; 4. Complete functions: can measure regularly, build 30 sets of test programs, access 30 sets of measurement data, display viscosity curve in real time, print data and curves, etc.; 5. Front level: intuitive and convenient level adjustment; 6. Stepless speed regulation: RV1T series: 0.3-100 rpm, a total of 998 speeds RV2T series: 0.1-200 revolutions, a total of 2000 revolutions 7. Display the curve of shear rate versus viscosity: the range of shear rate can be set and displayed on the computer in real time; the curve of time versus viscosity can also be displayed 8. Standard USB interface: insert U disk to copy data directly 9. Optional Pt100 temperature probe: wide temperature measurement range, from -20 to 300 °C, temperature measurement accuracy of 0.1 °C; 10. Abundant optional accessories: special constant temperature bath for viscometer, constant temperature cup, printer, standard viscosity sample (standard silicone oil), etc.; 11. Chinese and English operating system.
