Overview
The NIRUN SNB-3 Digital Viscometer is a High Accuracy and versatile viscosity measurement instrument. It uses a 16-bit microcomputer processor as the core and is equipped with a high-subdivision drive stepper motor to ensure accurate and smooth speed and is not affected by changes in AC voltage and frequency. The instrument can be used in a single machine or can be connected to a micro printer and computer for data collection and analysis. Measurement performance is of a professional level.
Features
1. It can be used alone or connected to a micro printer and computer for data collection.
2. High subdivision drive stepper motor swirl/spin, the speed is accurate and stable, and the change of AC voltage frequency does not affect the accuracy of measurement viscosity.
3. For thixotropic non-Newtonian liquids, the timing function guarantees good conformity data.
4. LCD liquid crystal with blue backlight function, directly display viscosity, speed, percentile torque, rotor at the current speed can be measured maximum viscosity value, temperature value.
5. The viscosity value shows continuous change, and there is an alarm sound beyond the measurement range.
6. Optional SNB data collection and drawing software or micro monochrome printer.
7. Measurement and correction of instrument full scale and all gear Linearity are carried out through computer interface.
8. Standard RTD temperature Probe, real-time monitoring of sample temperature, accuracy of 0.1 ℃, temperature range of 0-100 ℃.
9. Using a 16-bit microcomputer processor as the core, high-subdivision drive stepper motor, digital LCD with blue backlight function.
10. According to the needs, different standard rotors can be selected.
11. Optional Measurement Bureau reference material to calibrate Viscometer.
12. Optional SNB data collection and mapping software.
Principle
The instrument drives the rotor to swirl/spin in the sample through a stepper motor driven by high subdivision. Tack resistance to the rotor causes torque changes. The microcomputer processor collects and processes the torque signal, combines the rotor specifications and speed parameters, and accurately calculates the sample viscosity value, which is displayed in real time through the LCD screen. The standard RTD Temperature Probe monitors the sample temperature synchronously to ensure measurement accuracy.
Applications
Inks, Glue, Latex, Adhesive solvent, polymer solution, petroleum, paints, solvents, cosmetics, milk products, fruit juice
Steps
1. Select the appropriate rotor according to the measurement requirements and install it.
2. Pour the sample into a measurement container of suitable capacity.
3. Immerse the rotor into the sample at the specified mark.
4. Turn on the power supply and set the required speed through the instrument.
5. Start measurement, the instrument will automatically display viscosity, speed, torque, temperature and other data.
6. After the measurement is completed, record or collect data through external devices (such as printers, computers).
7. If you need timing measurement, you can set the timing function.
Notice
* Select the appropriate rotor and speed according to the sample viscosity range.
Make sure the rotor is clean and installed correctly.
* Sample temperature should be kept stable during measurement and can be monitored using the standard RTD Probe.
* Immerse the rotor to reach the specified mark to avoid bubbles.
* When the displayed value exceeds the measurement range, the instrument will issue an alarm prompt, and the measurement should be stopped and the parameters adjusted.
* Measurement calibration can be performed via computer interface. It is recommended to calibrate regularly with reference materials to ensure accuracy.
* Optional special viscosity thermostatic sink for precise control of sample temperature.
For small samples, small sample adapters and corresponding rotors can be purchased.
