Introduction: XNR-400B melt index is based on "GB / T 3682-2000 thermoplastic melt flow rate and melt volume flow rate measurement", "ISO 1133-2005 Plastics-Determination of the melt mass-flow rate (MFR ) and the melt volume-flow rate (MVR) and other standards designed and manufactured for the determination of thermoplastic melt flow rate of the instrument. The instrument uses the quality test; with automatic cutting device; with a micro-printer printout test results; with melt index calculation function, with FLASH memory, can store 20 test results. The instrument has the advantages of simple structure, convenient use, accurate measurement, stable and reliable performance. This instrument is not only suitable for the testing of plastics with lower melting temperature such as polyethylene, polypropylene, polystyrene and ABS resin, but also for the testing of engineering plastics such as polycarbonate, fluoroplastic and nylon with high melting temperature Is widely used in plastic production, plastic products, petrochemical and other industries and the relevant tertiary institutions, research institutes, commodity inspection departments. Features: 1, using liquid crystal display Chinese display, keyboard input, you can intuitively and easily set the time, temperature, sampling times. 2, 32-bit high-end microcontroller as the control core, computing speed, high data accuracy. Adopt ADC of 24 American AD Company, the temperature is collected fast, the collection precision is high, provided the physical assurance for the accuracy of the temperature control. 4, using embedded operating system, the internal task scheduling is reasonable, timing, delay and other control accuracy, to ensure temperature control, voice prompts and other operations accuracy. 5, can calculate, save, print test results. 6, the use of quality method (MFR) test. 7, automatic cutting during testing, manual adjustment when the instrument cut material. 8, The aircraft looks beautiful, reasonable design, stable performance, easy operation.
