Overview
HuiNuo RVDV-2 + SSA digital display Rotational Viscometer is a general-purpose intelligent digital Viscometer, using 16-bit microcomputer processor and stepper motor high subdivision drive, the range is 40~ 40000000 mPa · s, the whole process is continuously variable speed, Rotation speed is smooth. The LCD screen can display viscosity, Rotation speed, temperature, percentimeter torque, rotor number and the maximum viscosity value of the selected rotor at the current Rotation speed. Among them, the RVDV-2 type can also display shear rate and shear stress. The circuit adopts patch technology, which is compact and reasonable in layout.
Features
1. Adopt 16-bit microcomputer processor core control circuit and stepper motor high-subdivision drive
2. Wide range, stepless speed change, Rotation speed is stable
3. The LCD screen directly displays the viscosity, Rotation speed, temperature, percentile torque, rotor number and the maximum viscosity value of the selected rotor at the current Rotation speed
4. RVDV-2 type can display shear rate and shear stress
5. The circuit adopts chip technology, with a compact structure and reasonable layout
6. Configure a small number of sample adapters, the sample volume is only 10~ 20mL, suitable for expensive sample testing
7. Thermostatic bath can be connected to external circulation to control sample temperature
8. Easy to disassemble and clean
9. Optional data collection analysis and drawing software, connect the computer for automatic data collection and storage
Principle
Tack resistance and dynamic viscosity are measured using the swirl/spin Measuring method. A stepper motor is used to drive the rotor to swirl/spin in the liquid. Sensor data is processed by a microcomputer processor to calculate and display viscosity and other related parameters.
Applications
Oil, paints, food, paper, cosmetics, chemicals, coatings, capsules, asphalt, hot glue, paraffin, high polymers
Steps
1. Connect the Dedicated Power Adapter
2. Select the appropriate rotor and install it
3. Pour the sample into a container with a sample volume of 10~ 20mL
