Overview
The NIRUN HBDV-E Digital Viscometer is a High Accuracy, wide range viscosity measurement instrument. It uses stepper motor direct drive, gearless design, accurate speed, and is equipped with LCD liquid crystal with blue backlit display for large information display. The instrument can be widely used in viscosity measurement of a variety of fluid materials.
Features
1. Optional DV data collection and program control software can measure rheological characteristics.
2. Display shear rate and shear stress.
3. Stepper motor direct drive, no gear, accurate speed.
4. LCD liquid crystal with blue backlight, displaying a large amount of information.
5. The maximum viscosity value of the rotor can be measured at the current speed.
6. The viscosity value shows continuous change.
7. There is an alarm sound beyond the measurement range.
8. Standard RTD Temperature Probe.
9. Standard bidirectional RS232 or 485 interface.
10. Computer full-scale linear correction.
11. AC Power Adapter 100V-240V, good anti-interference.
Principle
The digital Viscometer drives a stepper motor through a microcomputer control system, which drives the rotor to swirl/spin in the sample. Tack resistance (torque) to the rotor is accurately measured by the beryllium bronze torque material and the ruby bearing system, and converted into viscosity by the control system. The shear rate and shear stress can be displayed in real time during the measurement process, and the data is obtained by continuous acquisition.
Applications
Inks, Glue, Latex, Adhesive solvent, polymer solution, petroleum, paints, solvents, cosmetics, milk products, fruit juice

Steps
The information does not provide specific operation steps.
Notice
* When measuring, make sure that the sample volume is in the range of 300~ 600ml, or use a 400/800ml self-contained container.
* Please select the appropriate rotor according to the measurement range before use (standard 2 #, 3 #, 4 #, 5 #, 6 #, 7 #, 1 #is optional).
* Power frequency in the range of AC100-240V, 50Hz/60Hz.
* If the measurement exceeds the range of the instrument, there will be an alarm sound, and the rotor or speed needs to be adjusted.
* For rheological characteristic measurement, DV data collection and programmable analysis software are required.
