LMI-4000 series MFI Melt Flow Indexer
Melt Flow Tester ( Indexer )
LMI-4000 series MFI Melt Flow Indexer
The LMI 4000 series are highly precise melt testing instruments for the measurement of melt flow rate (MFR) or melt volume rate (MVR) in quality control and research applications. The LMI 4000 is the first melt flow indexer to utilize a powerful 32 bit microprocessor to provide test parameter control, self-diagnostics and digital calibration. The on board computer controls and displays temperature to ± 0.1°C using a unique PID control algorithm.
Laboratory Melt Flow Tester (Indexer), with Electrical Weight Raising/Lowering System
We are pleased to announce the addition of two new features to the popular LMI4000 Series Melt Flow Testers. In addition to the previously available pneumatic weight raising and lowering system, a new electric weight raising and lowering system is now available. This electric system is ideal for applications requiring the use of heavy weights, but where shop air is not readily available. LMI4000 also offers an "auto cut-off" feature that automates the manual ASTM D1238 test method ‘A’. With this feature, a solenoid driven knife automatically cuts the extrudate as it leaves the melt indexer die at operator programmed intervals during the test. This new automated system removes the influence of the operator from test method ‘A" and makes test results more repeatable. LMI4000 features a 32-bit microprocessor that enables unparalleled control of material test parameters as well as the ability to perform self-diagnostics and digital calibrations. The instrument offers simple push-button RTD calibration and is available with an optional digital encoder for precise measurement of piston displacement and rate of descent. Personal computer communications capability and the company’s MIWORKS for Windows™ software, which acts as a melt index test database, are also available.
Features of LMI4000 Series Melt Flow Tester:
- Advanced microprocessor controlled design
- Excellent Price/Quality Ratio
- Performance to international standards
- Self-diagnostics capability
- Comprehensive statistical analysis package
- Simple push-button RTD calibration
- Smart keys for easy programming
- Made in USA
