The WKT-400T touchscreen melt flow indexer (melt index tester) measures melt flow rate (MFR) by the mass method. With a large touchscreen display and operation plus an integrated manual/automatic cutting design, it is designed and built to authoritative standards for determining the melt flow rate (MFR) of various plastics and resins in the viscous-flow state. It is widely used in plastics production, plastic products, and petrochemicals, as well as by universities, research institutes, and commodity inspection departments.
