Overview
JINGTIAN HBDV-2H digital display swirl/spin high temperature Viscometer is an instrument for measuring the viscosity of liquid substances at high temperature. It is mainly suitable for solid and heated liquid substances at room temperature, such as asphalt, hot-melt adhesive, polyethylene (PE) wax, etc. The instrument can be operated on a single machine, and the data can be displayed directly. It can also be equipped with software for data collection and full viscosity-temperature Linear dispersion monitoring. High subdivision stepper motor is used to ensure accurate and smooth Rotation speed, and computer correction is used to ensure Measurement accuracy.

10. Speed regulation mode: Rotor speed 0.1~ 200rpm stepless speed change.
Principle
The Viscometer works based on the principle of swirl/spin viscosity measurement. The instrument drives the rotor to swirl/spin in the sample, and the viscosity of the sample is calculated by measuring the resistance (torque) of the rotor to swirl/spin in the fluid. The high temperature furnace uniformly heats the embedded sample as a whole, so that the solid sample is melted into a liquid state. The stepper motor provides accurate and stable Rotation speed. The Sensor converts signals such as torque into electrical signals. After being calculated and processed internally by the instrument, it is directly displayed on the LCD screen in the form of viscosity values.
Applications
Asphalt, hot-melt adhesive, polyethylene (PE) wax and other solid and high temperature liquid substances viscosity measurement
Standards
The data did not mention specific compliance criteria
Steps
1. According to the estimated viscosity of the sample, choose the appropriate rotor (21 #, 27 #, 28 #, 29 #).
Add 10 to 20 mL of sample to the sample cup.
3. Install the selected rotor and place the sample cup in a high-temperature furnace.
4. Measuring temperature (RT + 10~ 250 ℃) by temperature controller.
5. Start the heating and wait until the sample melts and reaches the set temperature and is stable.
6. Set the required Rotor speed on the instrument (0.1~ 200rpm continuously variable speed).
7. Start swirl/spin measurement, the instrument LCD screen will directly display viscosity, Rotation speed, temperature, torque and other data.
8. If you need to record the whole data, you can connect the optional "data collection analysis and mapping software" for collection and analysis.
9. After the measurement is complete, close the instrument and clean the rotor and sample cup.
Notice
• The power supply of the instrument is 220V 50Hz, please ensure that the power supply matches.
• When selecting a rotor, refer to its maximum viscosity value that can be measured at this Rotation speed to avoid triggering an alarm beyond the range.
The sample capacity should be controlled between 10 and 20 milliliters.
• During the heating and measurement process, the high temperature furnace and the sample are in a high temperature state, please pay attention to the safety of operation and avoid burns.
• Ensure that the rotor is firmly installed, the sample temperature reaches the set value and stabilizes before starting the measurement to ensure the accuracy of the data.
Measurement range of the instrument will emit an alarm sound, need to adjust the rotor or Rotation speed in time.
• After use, the rotor and sample cup should be cleaned in time to prevent the sample residue from affecting the subsequent measurement.
• Optional software functions need to be configured separately, and data Linear dispersion monitoring cannot be performed when using a single machine.
