Drawell LVDV-1H High-Temperature Digital Viscometer

Drawell LVDV-1H High-Temperature Digital Viscometer

Product overview

The LVDV-1H High-Temperature Digital Viscometer is designed for materials that become low- to medium-viscosity liquids after heating. It is especially suitable when the sample viscosity drops significantly after melting or heating and a high-viscosity HBDV model would provide an unnecessarily high measuring range.

The Drawell LVDV-1H High-Temperature Digital Viscometer supports research, clinical, pharmaceutical, industrial, and quality-control laboratories. Scientific China provides model selection, configuration review, export coordination, and formal quotations.

Key features

• The main measurement is solid at room temperature and liquid after high temperature heating, such as asphalt, hot melt adhesive, polyethylene wax and so on.
• The measured data can be displayed directly on the LCD screen without secondary calculation. < VSoft Viscometer Data Collection,Analysis and Graphing Software > can also be selected to realize data acquisition and analysis and to compile the viscosity-temperature curve.
• High subdivision stepper motor, accurate and stable speed.
• LCD liquid crystal with blue backlight function can directly display the viscosity, speed, percentile torque, spindle number and the maximum viscosity and temperature of the selected spindle at the current speed. DV-2 series can also show shear rate and shear stress. Viscosity value shows continuous change, beyond the measurement range there is an alarm sound prompt.
• The measuring performance of the instrument has reached the level of the same type of products abroad through computer correction accuracy.
• High-temperature furnace uses embedded integral heating, uniform heating and small thermal inertia.
• Place approximately 10–20 mL of sample into the high-temperature sample container.
• Heat the sample to the required measurement temperature.
• Install a suitable spindle and set the rotational speed according to the expected viscosity.
• Confirm that temperature and viscosity readings have stabilized before recording the result.
• Read the result directly from the display or use optional VSoft software for data collection and viscosity–temperature analysis.
• For reliable viscosity results, select a spindle and rotational speed that keep the displayed torque within the recommended measuring range.
• Target Torque: 20–90%
• If torque is too low, use a larger spindle or higher speed. If torque is too high, use a smaller spindle or lower speed.

Applications

• Controlled heating, cooling, incubation, drying, or storage
• Sample preparation and temperature-sensitive laboratory workflows
• Routine research, testing, and quality-control applications
