Overview
NIRUN NDJ-5S + RTD Digital Viscometer is a High Accuracy viscosity measurement instrument with microcomputer control. It uses a high subdivision drive stepper motor to rotate accurately and smoothly, and an optional RTD temperature probe to monitor the sample temperature in real time, suitable for a variety of fluid viscosity measurement.
Features
1. Adopt patented technology to realize single-turn multiple sampling and overcome the drawbacks of single-turn single sampling.
2. High-subdivision drive stepper motor direct drive, accurate, smooth, no noise, no jitter, and not affected by AC voltage frequency changes.
3. With timing function, good conformity data can be obtained for thixotropic non-Newtonian liquids.
4. LCD liquid crystal with blue backlight, directly display the viscosity, speed, percentile torque and the maximum measurable viscosity value under the current Rotor speed, the viscosity value changes continuously, and there is a sound and light alarm for exceeding the range.
5. Computer full scale linear correction, Measurement accuracy is +/- 1.0% of full scale.
6. Adopt switching power adapter, wide power input, good anti-interference.
7. Optional RTD temperature probe can be used to monitor the sample temperature in real time.
8. Optional RS232 interface to connect the micro printer to print measurement data in real time.
Principle
The instrument drives a high-subdivision stepper motor through a microcomputer control system to drive the rotor to swirl/spin at a uniform speed in the sample. Tack resistance to the rotor forms a torque, which is detected by the Sensor and processed internally by the instrument. Finally, the viscosity value of the sample is directly displayed on the LCD screen. The continuous collection method can more accurately reflect the viscosity change.
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 according to the estimated viscosity.
2. Connect the rotor to the instrument and immerse the sample to be tested to the specified marking line.
3. Turn on the power and set the required measurement speed.
4. Start the measurement and read the viscosity data after the display value is stable.
5. To monitor the temperature, connect the RTD temperature probe.
6. After the measurement is completed, clean the rotor.
Notice
Please read the instructions carefully before use.
* Ensure that the rotor is clean, drying and not damaged, and installed firmly.
The sample volume should be sufficient to submerge the rotor to the designated marking line.
* The instrument should be kept level and stable during measurement.
* Avoid running for a long time in an out-of-range or instrument alarm state.
The timing function is used rationally according to the nature of the sample (e.g. thixotropic).
* Before connecting or disconnecting accessories, please turn off the power.
* Please store instruments and accessories in a drying place.
