Overview
SNB-AI intelligent digital Viscometer is a digital display Rotational Viscometer with 16-bit microcomputer processor core control circuit and gearless drive. The instrument has intelligent automatic measurement and manual measurement functions. The blue screen LCD screen can directly display viscosity, speed, temperature, percentile torque, rotor number and the maximum viscosity value of the selected rotor at the current speed. Sample demand is small, only 10-20ml. The instrument can measure the Tack resistance and dynamic viscosity of liquids. Measurement performance and function are close to the professional level of foreign congeneric products.
Features
Adopt 16-bit microcomputer processor core control circuit, no gear drive, compact structure, reasonable layout.
2. With intelligent automatic measurement and manual measurement in two ways.
3. Blue screen LCD digital display, directly display viscosity, speed, temperature, percentile torque, rotor number and the maximum viscosity value of the selected rotor at the current speed.
4. The sample demand is small, only 10-20ml is required.
5. Can be equipped with "data collection and drawing software" to achieve data collection, preservation, historical data comparison and a number of mathematical statistical analysis tasks.
6. Measurement accuracy is high (+/- 1% F. S), reproducibility is good (+/- 0.5% F. S).
7. Rotor speed support 0.1~ 200rpm stepless speed.
Principle
The instrument drives the sensor pointer with a high-subdivision stepper motor, and drives the rotor swirl/spin through the hairspring and shaft. If the rotor is not subject to liquid resistance, the hairspring Sensor pointer is in the same position as the stepper motor Sensor pointer. If the rotor is subject to liquid viscous resistance, the hairspring generates torque to compete with it until equilibrate. At this time, the photoelectric Sensor processes the signal output to a 16-bit microcomputer processor, and finally displays the viscosity value of the liquid (mPa · s) on the LCD screen.
Applications
Oil, paints, food, paper, cosmetics, chemicals, coatings, capsules and other fluid viscosity measurement. With a special temperature-controlled heater can be used to measure asphalt apparent viscosity, hot-soluble glue, paraffin, high polymer and other fluid viscosity.
Steps
1. Select the appropriate rotor according to the measurement requirements (such as 21 #, 27 #, 28 #, 29 #).
2. Prepare 10-20 ml of the sample to be tested.
3. Install the rotor on the instrument shaft.
4. Immerse the rotor into the sample at the specified mark.
5. Select Manual measurement or Automatic Measurement mode.
6. Set the required speed through the instrument (0.1 to 200rpm continuously variable speed).
7. Start the measurement, the instrument will automatically process the data and display the results (viscosity, rotational speed, temperature, torque, etc.) on the screen.
8. If you connect the data collection software, you can automatically record, analyze and generate charts.
Notice
Please use the instrument-specific power adapter (input 100~ 240V, 50~ 60Hz).
* According to the estimated viscosity range of the tested sample, select the appropriate rotor model and speed to ensure Measurement accuracy.
* Ensure that the rotor is clean, drying and firmly installed to avoid measurement errors.
When immersing in the rotor, the sample liquid level should reach the marking line on the rotor rod, and ensure that the rotor is in the center of the sample to avoid touching the container wall.
* When measuring high viscosity samples or using small rotors, pay attention to the torque percentage display of the instrument to avoid over-range operation.
* For accurate temperature-related measurements, it is recommended to use it with a dedicated temperature-controlled heater.
* When using the data collection software, please ensure that the connection between the computer and the instrument is stable and follow the software instructions.
