HBDV-2H High-Temperature Digital Viscometer

The HBDV-2H High-Temperature Digital Viscometer is designed for viscosity measurement of materials that need to be melted or maintained at elevated temperatures during testing. It suitable for asphalt, hot melt adhesives, polyethylene wax and other high-viscosity melt materials.

Compared with the HBDV-1H, the HBDV-2H offers a lower starting viscosity range, higher maximum speed and additional shear rate / shear stress display for more detailed viscosity evaluation.

Features of HBDV-2H Digital Viscometer

  1. 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.
  2. 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.
  3. High subdivision stepper motor, accurate and stable speed.
  4. 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.
  5. The measuring performance of the instrument has reached the level of the same type of products abroad through computer correction accuracy.
  6. High-temperature furnace uses embedded integral heating, uniform heating and small thermal inertia.

How to Operate High-Temperature Digital Viscometer?

Prepare the Sample

1. Prepare the Sample

Place approximately 10–20 mL of sample into the high-temperature sample container.

Set the Test Temperature

2. Set the Test Temperature

Heat the sample to the required measurement temperature.

Select Spindle and Speed

3. Select Spindle and Speed

Install a suitable spindle and set the rotational speed according to the expected viscosity.

Allow the Reading to Stabilize

4. Allow the Reading to Stabilize

Confirm that temperature and viscosity readings have stabilized before recording the result.

Record or Export Data

5. Record or Export Data

Read the result directly from the display or use optional VSoft software for data collection and viscosity–temperature analysis.

How to Choose Spindle and Speed？

Target Torque 20–90

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.

FAQ

The HBDV-2H is designed for medium- to high-viscosity materials that require heating during measurement, including asphalt, hot melt adhesives and polyethylene wax.

The measuring range is 400–80,000,000 mPa·s.

The temperature control range extends from approximately 10°C above ambient temperature to 300°C.

HBDV-2H provides a wider low-end measuring range of 400 mPa·s, speeds up to 200 RPM and shear rate / shear stress display. HBDV-1H starts from 800 mPa·s and operates up to 99.9 RPM.

Approximately 10–20 mL is required for measurement.

For reliable measurement, the displayed torque should generally remain between 20% and 90%. If it falls outside this range, adjust the speed or spindle.

Yes. Optional VSoft software supports data collection, analysis and viscosity–temperature curve generation.
