Overview
The NIRUN SNB-1 (custom) digital Viscometer is a precision measuring instrument controlled by a microcomputer processor. It can be used in a single machine or connected to a micro printer and computer for data collection and analysis, and is widely used in the measurement of the viscosity of a variety of fluids.
Features
1. Using a 16-bit microcomputer processor as the core, high-subdivision drive stepper motor, accurate and stable speed, not affected by AC voltage frequency changes.
2. LCD LCD screen with blue backlight, direct display viscosity, speed, torque percentage, maximum measurable viscosity and temperature value, viscosity value continuous change.
3. With timing function, the conformity of measurement data can be guaranteed for thixotropic non-Newtonian liquids.
4. Standard RTD temperature probe, real-time monitoring of sample temperature, accuracy 0.1 ℃, range 0-100 ℃.
5. Measurement and correction of full scale and all file Linearity are carried out through computer interface, and the performance reaches professional level.
6. When the measurement exceeds the range, there is a sound and light alarm prompt.
7. Accessories such as different standard rotors, reference materials, data collection software and micro printers can be selected according to needs.
Principle
The instrument drives the rotor to swirl/spin at a uniform speed in the sample through a high-subdivision drive stepper motor. The Tack resistance moment received by the rotor is detected by the Sensor and converted into an electrical signal. After processing by the microcomputer processor, the viscosity value of the sample is directly calculated and displayed. At the same time, the RTD temperature probe monitors the sample temperature in real time.
Applications
Inks, Glue, Latex, Solvent Adhesive, Polymer Solution, Petroleum, paints Coatings, solvents, cosmetics, milk products, products, juices
Steps
1. Choose the appropriate rotor and speed combination according to the estimated viscosity value.
2. Install the rotor and inject the sample into the measurement vessel to the specified scale.
3. Immerse the rotor into the sample to a specified depth.
4. Turn on the power and set the required measurement parameters (such as speed, timing, etc.).
5. Start the measurement, the instrument automatically runs and displays real-time viscosity, temperature and other data.
6. After the measurement is completed, read and record the stable displayed viscosity value.
7. If you need data recording, you can connect a printer to print or collect data through software.
Notice
Please ensure that the instrument is placed horizontally before use.
* Correctly select the rotor and speed according to the sample viscosity range to avoid over-range measurement.
The rotor immersion depth and sample volume must meet the specified requirements.
During the measurement process, the sample temperature should be kept stable.
* When the instrument alarms, the measurement should be stopped immediately and checked for out-of-range or Miscellaneous abnormalities.
* Clean the rotor and measurement parts in time after use.
Instruments are regularly calibrated using reference materials to ensure measurement accuracy.
When connecting external devices (e.g. printers, computers), please ensure compatibility and follow the instructions.
