The GÖTTFERT MI-3 is a semi-automatic machine with fix installed measuring weights matching the highest standards.
The MI-3 melt index tester (plastometer) has an integrated, fully loaded weight magazine with electrical weight lifting and manual weight selection.
Due to the high-precision displacement sensor, even very low or very high MFR/MVR-values can be recorded with high precision. The external piston guidance on the guide rod of the test weight makes it possible to measure even very sticky materials with high repeatability. The test chamber with exchangeable test barrels can be swivelled out for easy filling and cleaning.
The device offers users in quality control and incoming goods inspection the possibility to automatically perform MFR or MVR measurements according to ISO 1133 Procedure B as well as ASTM D1238 Procedure B. With an optional cutting device, the measurements can also be evaluated according to ISO 1133 Procedure A and ASTM D1238 Procedure A. With special capillaries, measurements can also be performed according to ASTM D1238 Procedure C ("half-die") or ASTM D3364.
In addition to the standardized MFR and MVR measurements according to ASTM and ISO, GÖTTFERT Plastometers have various add-ons which offer additional functionality.
Directly connected laboratory scale for determination of the melt density.
The residual moisture has a considerable influence on the measurement result for certain test materials. Therefore, it is recommended to dry test materials before a IV measurement and to determine the residual moisture.
The measuring head is mounted below the die. The measurement can be carried out parallel to a viscosity measurement.
