Melt Flow Index Tester comes with tools, piston and dies, integrated microprocessor based PID temperature controller. The Flow Index Tester is designed for measuring melt flow rate with high accuracy. The Flow Index Tester is used for quality control test on flow ability, grading of thermoplastic materials according to flow. The Melt Flow Index Tester is designed to calculate accurate rate of extrusion of molten resin through an orifice of specified temperature and pressure.
