Used to determine the flowability of thermoplastic polymers at high temperatures, such as polyethylene, polypropylene, polyoxymethylene, ABS resin, polycarbonate, nylon fluoroplastics, and other polymers.

The XNR-400C model adopts an industrial PLC programmable controller, a LCD operating platform, and a separate temperature control unit LED digital display for temperature control. The machine adopts a dual control system that combines host control and computer display operation. The automatic temperature control is divided into three cutting methods: manual, time control, and automatic. It can achieve two testing methods: mass method (MFR) and volume method (MVR); This machine can measure the melt density of raw materials at the test temperature, and the system also has temperature calibration function. The system can store and print test data.
