Overview
The NIRUN LDV-T1 digital Viscometer is an integrated viscosity measurement and temperature control machine. It breaks through the traditional split machine mode composed of thermostatic sink, Viscosity-Tester and small sample adapter, and realizes the integration of measurement and temperature control.
Features
The measurement system composed of a small sample adapter (SSR) and SC4 rotor can perform accurate measurement at a certain shear rate, and the sample dosage is only 2-16ml.
2. Small sample cylinders are easy to handle and easy to clean.
3. The small sample cartridge is tightly connected to the temperature controller to achieve accurate sample thermostatic.
4. Stirring the rotor with a small amount of sample can minimize the temperature inhomogeneity of the sample and greatly shorten the thermostatic time.
5. Temperature control during measurement helps to ensure the accuracy of the results, and the temperature control accuracy reaches +/- 0.1 ℃.
6, temperature control is operated by DV-T1 data collection and drawing software, with good operation performance and flexibility.
Principle
The Viscometer uses the swirl/spin method for viscosity measurement. A microcomputer control system drives the rotor in the sample at a set speed (0.1-100 rpm, continuously variable speed) swirl/spin, measuring the torque generated by the sample on the rotor to calculate the viscosity value. At the same time, the integrated semiconductor temperature control system performs precise temperature control of the sample barrel to ensure that the measurement is carried out under thermostatic conditions.
Applications
Laboratory, scientific and industrial areas requiring accurate measurement of viscosity and temperature control
Steps
1. Install and connect the device.
2. Set the required measurement parameters (such as speed) and temperature control program through software.
3. Inject 2-16 ml of sample into the sample sleeve of the Small Sample Adapter (SSR).
4. Install the SC4 rotor in place.
5, start the equipment, the system will automatically carry out temperature control and viscosity measurement.
6. View and analyze data in real time through DV-T1 data collection and mapping software.
Notice
• Make sure the Power frequency is in the AC100-240V range and matches the corresponding frequency (50Hz/60Hz).
• Please select the appropriate rotor model according to the measurement range before use (standard configuration is SC4-21, 27, 28, 29, optional Miscellaneous model).
• The sample volume should be controlled between 2-16ml to ensure measurement accuracy.
• Be careful when loading and unloading small sample cylinders and rotors.
• Regularly clean the sample cartridge and rotor to avoid residues affecting the measurement results.
Do not use the temperature control function outside the temperature range of -1 ° C to 150 ° C.
• When operating the software, follow the software guidelines for parameter setting and data collection.
