ZNN-D12 Digital-second speed rotational viscometer

1. ZNN-D12-speed super digital viscometer measurement of the rheological parameters can be measured, according to drawing more flow curves measured values to determine the flow of process liquid flow pattern, choose the appropriate formula for non-Newtonian fluid a more accurate measurement, the rheological parameters of drilling fluids for field research and analysis at the same time, can be dynamic and static shear strength, flow index and consistency coefficient of determination of a series of technical parameters. Conducive to safe, fast, scientific drilling needs. Is easy to operate, test accuracy, wide measurement range of features. 
2. The machine uses high-breakdown motor drives, stepper motor with the motor torque, speed and accurate and smooth. 
3. Stepper motor belt drive, low noise, easily adjusted. 
4. Viscosity measured by imports of digital sensors, measurement accuracy, stability, good anti-interference sensor. 
5. Large blue LCD touch screen display, a direct digital display viscosity, speed, time, and whether to save. 
6. Zero calibration. 
7. 20 groups of measurement data can be stored (including year, month date, sample number, viscosity, speed, time), power saving data is not lost.
