Overview
HuiNuo RVDV-2H digital display swirl/spin high temperature Viscometer is mainly used for the measurement of solid at room temperature and liquid after high temperature heating, such as asphalt, hot-melt adhesive, polyethylene (PE) wax, etc. The instrument can be used on a single machine to directly display measurement data without secondary calculation; it can also be equipped with data collection analysis and drawing software to monitor the viscosity-temperature Linear dispersion throughout the process, using high-subdivision stepper motors to ensure accurate and stable Rotation speed, LCD liquid crystal with blue backlight function Display a variety of parameters, Measurement performance reaches the level of foreign products of the same type through computer correction, high temperature furnace adopts embedded integrated heating, uniform heating and small thermal inertia.
Features
1. Can be used in a single machine, the measurement data is directly displayed on the LCD screen, no need for secondary calculation
2. Optional data collection analysis and drawing software to realize data collection and Data analysis, and monitor viscosity-temperature Linear dispersion throughout the process
3. High subdivision stepper motor, Rotation speed accurate and stable
4. LCD liquid crystal with blue backlight function, directly display viscosity, Rotation speed, percentile torque, rotor number and the maximum viscosity value and temperature value of the selected rotor at the current Rotation speed, DV-2 series can also display shear rate, shear stress
5. The viscosity value shows continuous change, and there is an alarm sound beyond the Measurement range
6. Measurement performance reaches the level of foreign products of the same type through computer correction accuracy
7. High temperature furnace adopts embedded integral heating, uniform heating, small thermal inertia
Principle
Measurement principle of swirl/spin, using high subdivision stepper motor to drive the rotor in the sample swirl/spin, measurement of sample viscosity characteristics at high temperature. Viscosity value, Rotation speed, temperature and other parameters directly displayed on the LCD screen, and optional software to achieve data collection and Linear dispersion monitoring.
Applications
Asphalt, hot-melt adhesive, polyethylene (PE) wax
Steps
1. Prepare the sample with a capacity of 10~ 20mL
2. Select and install the appropriate rotor (21 #, 27 #, 28 #, 29 #)
3. Speed range is 0.1~ 200rpm CVT
4. Temperature range is room temperature + 10~ 250 ℃, temperature control accuracy +/- 0.1 ℃
5. Start measurement, the instrument directly displays viscosity, Rotation speed, temperature and other parameters
6. If the Measurement range is exceeded, the instrument will issue an alarm sound
Notice
• The sample capacity needs to be controlled within the range of 10~ 20mL
• Measurement accuracy of +/- 1% F. S and reproducibility of +/- 0.5% F. S for newtonian fluids
Measurement range beyond the instrument will emit an alarm sound, need to adjust the parameters in time
• Power supply voltage is 220V 50Hz to ensure stable power supply
• Pay attention to safety during high temperature operation to avoid burns
