XNR-400B Melt flow rate tester

1、 Instrument Overview
This machine is suitable for testing engineering plastics such as polyethylene, polyarylsulfone, fluoroplastics, nylon, etc. with high melting temperatures, as well as plastics with low melting temperatures such as polyethylene, polystyrene, polypropylene ABS resin, and polyoxymethylene resin. Especially suitable for use in colleges, research institutions, various quality inspection institutions, plastic production enterprises, plastic products, and the petrochemical industry.
2、 Instrument characteristics
The measured results can be automatically converted to each other, with a melt density testing function, one machine with multiple functions, and automatic timing, cutting, and result printing. The control software can achieve the setting of parameters, constant temperature control, material cutting, measurement calibration, timing, and display of MFR results. After the experiment is completed, the test data can be queried and printed. To prevent accidental operations, some important operations require password verification.
Full color touch screen, bilingual operation interface in both Chinese and English. The instrument has a compact and aesthetically pleasing structure, and a stable control system. Fast heating speed and small overshoot; High temperature control accuracy; After filling, it can quickly return to a constant temperature state. It has functions such as upper limit temperature protection, constant temperature alarm, and operation prompt. It is at a high level domestically and has passed the EU product CE certification.
3、 Compliant with standards
