Computer Control Hot Fluidity Melt Flow Index Tester

Computer control hot fluidity index/melt flow indexer

I General introduction:

The XNR-400E Melting Flow Rometer is an instrument designed and manufactured to GB/T3682-2018, ASTM D1238-98 standards and referring to similar standards such as JB/T5456, ISO1133 to determine the melt mass flow rate of thermoplastic plastics (MVR) and melt volume flow rate (MFR), measuring the melt mass flow rate by automatic sampling and scale weighing；The determination of the melt volume flow rate is through a photoencoder and an automatic timing system, first measuring the time required to move the specified distance of the piston, and then calculating the volume flow rate according to the formula.The final results of both assays are shown on the touch screen of the instrument and output by a microprinter, can also connect to Computer. The instrument is accurate, simple, intuitive and reliable. It is not only suitable for polycarbonate (PC), fluorine plastic, nylon, but also for the determination of lower melting temperatures such as polyethylene (PE), polypropylene (PP), polyformaldehyde (POM), polystyrene (PS) ABS resin, and polycarbonate.It is widely used in plastic production, plastic products, petrochemical and other industries, relevant colleges and universities, scientific research units and commercial inspection departments.

The XNR-400E melt flow rate meter is microcomputer controlled to manually or automatically cut off materials with two measures: MFR and MVR
