Melt Index MI-3 • The selected test weights are internally installed; manual and therefore dangerous weight handling is eliminated • Users may simply select test weights using a lever that activates the electrical weight handling system • A specially designed guidance system for the test weights ensures that measurements are not influenced by weights being slightly slanted, skew, or off center, which would lead to errors • To ensure convenient access to the test chamber, it can be swiveled by 45°. The use of a special cable system ensures many years of service and is especially designed to...

Loading functionality Compressing Many polymers are very sensitive when it comes to packing and pre-loading, where handling differences directly impact measurement accuracy and repeatability. The test devices offer different ways to pack and how to apply a pre-load to the test material. This control covers the complete pre-heat/melt time. Either the time spent on each is controlled, or the position of the piston /material at a specific point in the barrel. The loads used are chosen manually with the mi2.3 and MI-3, automatically with the MI-4. Melting time Post measurement First compression...

Load 1 Load 2 Load 3 Load 4 Load 1 Load 2 Load 3 Load 4 Relaxation area Load-Diagramm Conventional multiple load tests do not provide any relaxation phase while load changing: this results in higher dispersed test values compared to single test load measurements (figure at left). With our new multiple load function (up to 8 weights), being integrated in the MI-4, the material is given enough relaxation time between load changes to minimize any pre-shearing influences. The result is that both, single load tests and multiple load tests are now in high conformity (figure at right). Vergleich...

MFRView - Measure- and Visualization Program with Management-System The successor program package of MFRHost is used to configure and control the whole measurement process, the graphical presentation, the evaluation and of course the report generation. Many useful methods were integrated to fulfill the user demands. Comfortable functions, like for example only-mous-click paramterization as well as self definable menues make the preparation and measuring work easier and faster. The new Software, which is also available for previous melt index test device models, works with ACCESS® databases...
