Overview
JINGTIAN SNB-AIH digital display swirl/spin high temperature Viscometer is a precision instrument designed for the measurement of solid and high temperature liquid substances at room temperature (such as asphalt, hot-melt adhesive, polyethylene (PE) wax, etc.). It uses a high-subdivision stepper motor to ensure accurate and smooth Rotation speed, and is equipped with a backlit LCD LCD screen, which can directly display key data such as viscosity, Rotation speed, temperature, torque, rotor number and maximum measurable viscosity value. It supports stand-alone use or connection software for data collection and analysis.
Features
1. Direct display of measurement data, no need for secondary calculation, can be used alone.
2. Optional "data collection analysis and drawing software" to achieve data collection, analysis and full monitoring of viscosity-temperature Linear dispersion.
3. Using high subdivision stepper motor, Rotation speed is accurate and stable.
4. LCD liquid crystal with blue backlight, comprehensive display information, including viscosity, Rotation speed, percentile torque, rotor number, current Rotation speed can measure the maximum viscosity value and temperature value.
5. The viscosity value is displayed continuously, and there are sound and light alarm prompts beyond the Measurement range.
6. Measurement performance of the instrument is corrected by computer, and the accuracy reaches the level of foreign products of the same type.
7. The high-temperature furnace adopts built-in integrated heating, with uniform heating and small thermal inertia.
8. Support manual measurement and automatic measurement two modes, the speed regulation mode is continuously variable.
Principle
The Viscometer works on the principle of swirl/spin viscosity measurement. The instrument drives the selected rotor to swirl/spin in the sample, and the viscosity value of the sample is calculated by measuring the resistance (torque) of the rotor to swirl/spin in the fluid. The embedded sample is uniformly heated in the high temperature furnace as a whole, so that the solid sample is melted into a liquid state. The measurement data is collected by the Sensor, processed and corrected by the internal computer system, and displayed directly on the LCD screen.
Applications
Asphalt measurement, hot-melt adhesive measurement, polyethylene (PE) wax measurement
Steps
Prepare an appropriate amount (10~ 20mL) of sample into the measurement container.
2. According to the estimated viscosity range, select the appropriate rotor (21 #, 27 #, 28 #, 29 #) and install it.
3. Place the sample container in a high-temperature furnace and set the target temperature (RT + 10 to 250 ° C).
4. After the sample melts and reaches the set temperature, select Manual or Automatic Measurement mode.
5. Set the required Rotor speed (0.1~ 200rpm) by CVT.
6. Start measurement, the instrument screen will display viscosity, Rotation speed, temperature, torque and other data in real time.
7. After the measurement is completed, record the data. If the software is connected, data collection and Linear dispersion analysis can be performed simultaneously.
Notice
• Power supply voltage is 220V 50Hz and properly grounded.
• According to the estimated viscosity of the sample, select the appropriate rotor and Rotation speed combination to ensure that the Measured value is within the instrument range (50~ 10000000mPa · s).
• The sample size is recommended to be between 10 and 20mL to ensure that the rotor immersion depth is appropriate.
• During high temperature operation, pay attention to the temperature of the high temperature furnace and sample container to avoid burns.
• When the instrument alarm prompts, please check whether the Measurement range is exceeded or Miscellaneous abnormality occurs.
• Keep the rotor clean and clean it in time after measurement to avoid affecting the next Measurement accuracy.
• When not in use for a long time, please keep it in a drying environment.
