The Melt Flow Index intrument MI-4 enables to measure the melt-flow-rate (MFR) and the melt-volume-rate (MVR) with a semi-automatic instrument. This unique melt index instrument can carry out a single weight test according to ISO 1133 and ASTM D1238, procedures B, as well as ISO 1133 and ASTM D1238 Procedure C for the "Half Height / Half Diameter" standard.
The MI-4 is equipped with a weight cartridge, to enable the operator an opportunity to choose the measuring weight automatically. The high resolution position sensor with an automatic selection of the resolution allows a repeatable, reliable determination of MFR and MVR. The Tests can vary from one test loads (single load mode) to several test loads per barrel filling (multiple test load mode).
