Stepless debugging, can measure super high viscosity of the sample. 5-inch color touch screen can be comprehensive, visual display of a variety of parameters and working conditions. It has many advantages, such as many measuring parameters, rich display content, convenient operation, intuitive reading, high measuring precision, stable rotational speed, strong anti-interference performance, showing the curve of shear rate and viscosity, and so on.

Digital Rotational Viscometer LVDV-1T for Lab Battery Slurry Testing

Main feature:
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 easily;
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 (graphic display), range overflow alarm, automatic scan, current rotor Maximum measurement range, date, time, etc. under the combination of speed. And 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, with a total of 998 speeds RV2T series: 0.1-200 rpm, with a total of 2000 speeds
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. Rich optional accessories: special constant temperature bath for viscometer, constant temperature cup, printer, standard viscosity sample (standard silicone oil), etc.;
11. Chinese and English operating systems (pre-set before leaving the factory).
