Overview
The LVDV-1H digital display swirl/spin high temperature Viscometer is an instrument under the JINGTIAN brand. It is mainly used for the measurement of substances that are solid at room temperature and heated to liquid at high temperature, such as asphalt, hot-melt adhesive, polyethylene (PE) wax, etc. The instrument can be used on a single machine, and the measurement data is directly displayed on the LCD screen without secondary calculation. It can also be equipped with optional data collection analysis and mapping software to realize data collection and monitor the viscosity-temperature throughout the process. Linear dispersion.
Features
1. Using high subdivision stepper motor, Rotation speed is accurate and stable.
2. 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 under the current Rotation speed.
3. The viscosity value shows continuous change, and there is an alarm sound beyond the Measurement range.
4. Measurement performance of the instrument is corrected by computer, and the accuracy reaches the level of foreign products of the same type.
5. The high-temperature furnace adopts built-in integrated heating, with uniform heating and small thermal inertia.
6. Can be used alone, or optional software to achieve data collection analysis and full monitoring.
Principle
The instrument drives the rotor to swirl/spin in the sample through a high-subdivision stepper motor, measures the Tack resistance of the rotor at a specific Rotation speed, and converts it into a viscosity value for direct display. With the built-in integral heating high temperature furnace, the sample can be precisely controlled within a set Temperature range, so as to measure the viscosity characteristics of the substance in the high temperature liquid state.
Applications
Asphalt, hot-melt adhesive, polyethylene (PE) wax and other solid and high temperature liquid substances viscosity measurement
Steps
1. According to the estimated viscosity of the sample, choose the appropriate rotor (No. 21, 27, 28, 29).
Put an appropriate amount of sample (10-20mL) into the measurement container.
3. Install the rotor and place the measurement assembly in the high temperature furnace.
4. Set the target temperature (room temperature + 10 ° C to 250 ° C) through the temperature controller.
5. After the sample temperature reaches the set value and stabilizes, set the required swirl/spin speed (0.1-99 rpm continuously variable speed) on the instrument.
6. Start the measurement, the instrument LCD screen will directly display viscosity, Rotation speed, temperature, torque and other data.
7. After the measurement is completed, the data can be recorded or collected and analyzed through optional software.
Notice
Please ensure that the power supply is 220V 50Hz.
* Choose the right rotor based on the estimated viscosity to ensure that the Measured value is within range.
The recommended sample capacity is between 10 and 20 milliliters.
The setting temperature should be within the range of room temperature + 10 ° C to 250 ° C.
* For measurement, wait until the sample temperature reaches the set value and stabilizes before starting the swirl/spin measurement.
* When the viscosity display value exceeds the maximum measurable range of the selected rotor at the current Rotation speed, the instrument will issue an alarm.
* Instrument reproducibility is +/- 0.5% F.S., Measurement accuracy is +/- 1% F.S. (for newtonian fluids).
