Touch Screen Color Display Integrated Automated Multi-weight System
The Melt Flow Indexer is related to the melted material viscosity. It allows the operator to make an estimation of “Mean molecular weight”, at the same time giving an indication of melt “flow ability” through a die.
The Melt Index is defined as the weight or the volume of melted material flowing through a calibrated die, under the effect of a pre-determined force, at constant temperature and for the total time of 10 minutes.
A user friendly instrument with innovative specifications Integrated automated Multiweight system
Built in weights (all weights confirm to International standards). The weight or the weights (max. 4) are automatically selected by a simple touch of the operator on the screen. In case of multi-weight testing the choice can be for incremental or decrement testing. No manual weight handling is required.
The basic instrument has a wide color touch screen for a simple and fast input of the test parameters, visualization of test execution and final results. The instrument can be connected to a PC through a RS232 port for direct acquisition of the test parameters and test results which can be directly saved or exported with the SW included in the supply. Also, data can be saved directly on an USB memory and downloaded in a remote PC. The software package provided with the instrument does not require any license; hence multiple installations can be made in case of multiple operators.
The multi-weight test (up to 4 weights during the same test in an increasing or decreasing mode) allows for calculation of the following results to indicate the rheological properties of material:
- FFR ( MFR ratio with different weights)
- Shear Stress
- Shear Rate
- Apparent viscosity
- Diagram MFR vs. Time
- Diagram MVR vs. Time
