Product Overview
The Pingxuan DV-IICPRV Cone and Plate Viscometer is a precision instrument designed for viscosity measurement with small sample volumes, requiring only 0.5-2.0 mL. It features an advanced CORTEX-A7 core and a LINUX operating system, equipped with a 7-inch color LCD touchscreen. The user interface is simple and clear, enabling quick and convenient test creation, data collection, and viscosity measurement. The instrument also offers programming capabilities and result analysis functions, supporting data averaging and QC upper/lower limit alerts. Test data can be transmitted or exported through various methods.
Product Features
1. Equipped with a 7-inch full-color touchscreen display, supporting multiple language interfaces including Chinese/English/Japanese/Korean, with real-time trend display.
2. Enhanced safety control, supporting customizable user permissions, and recording of test dates and times.
3. Built-in multiple options, including temperature control, timed measurements, user-defined speed/rotor lists, and programmable QC upper/lower limits/alarms.
4. Comprehensive display information, including viscosity, kinematic viscosity, temperature, shear rate/shear force, % torque - speed/rotor, and program step status.
5. Designed specifically for small sample volumes, requiring only 0.5~2.0 mL of sample, with rapid temperature stabilization.
6. Provides USB/RS232 interfaces, with optional computer control software for remote automatic control and data acquisition, or direct connection to a mini printer.
7. Optional temperature probe (built into the sample cup) and dedicated viscometer constant temperature water bath for precise sample temperature control and measurement.
8. Provides precise shear rates for determining the rheological curve of samples.
9. Test accuracy is ±1.0%, with a temperature control range of 5°C to 80°C.
Working Principle
The cone-plate viscometer operates based on the principle of the cone-plate measurement system. The instrument drives a conical rotor to rotate on a flat plate filled with the sample, and calculates the viscosity of the sample by measuring the resistance (torque) experienced by the rotor at a specific rotational speed. Due to the precisely designed cone-plate gap, which provides a uniform and known shear rate, the viscosity can be accurately determined, and rheological curves can be plotted. The instrument controls the entire measurement process through its built-in advanced processor and operating system, while displaying and recording relevant data in real-time.
Application Areas
Suitable for fields requiring viscosity measurement of small sample quantities, such as scientific research, laboratories, and quality control.
Complies with standards
Not mentioned.
Operation Steps
1. Prepare 0.5-2.0 mL of the sample to be tested.
2. Select or create a test program via the 7-inch touchscreen, and set parameters (such as speed, temperature, QC limits, etc.).
3. Install the appropriate cone rotor and inject the sample into the measurement system.
4. Start the test, and the instrument will automatically perform measurements while displaying data and trends in real time.
5. After the test is completed, data can be transferred to a computer, printed via a mini printer, or exported via a USB drive.
Precautions
* The instrument comes standard with one user-selected cone rotor, while other rotors need to be purchased separately.
* Temperature probes, sample cups with temperature probes, constant temperature water baths, remote control software, standard solutions, etc., are all optional accessories and should be selected based on specific needs.
* When using remote control software, connect the instrument to a computer to enable automatic control and data acquisition and analysis.
* Ensure the sample volume is within the range of 0.5–2.0 mL to obtain accurate measurement results.
* For temperature-controlled measurements, connect the optional constant temperature water bath or sample cup with a temperature probe.
