XNR-400C price plastic melt flow index tester/used melt flow index

       XNR-400C Melt Flow Indexer is an instrument used to indicate the MFR and the MVR of thermoplastic                plastic, which is designed and produced according to the standards like GB/T3682-2000, ASTM D1238-          98, JB/T5456,  ISO1133, etc. When measuring MFR, the specimen is cut automatically, the time interval of        cutting specimen is controlled by PLC and the weight is measured by the balance. When  measuring MVR,        with the displacement  measured through photoelectric encoder and the time measured matically, the                needed time for the piston to move a required distance is measured first and  the MVR could be figured            out through the formula. Both of the results of MFR and MVR will be displayed on the touch screen and            printed out by the micro-printer. The measured data is very accurate, the operation is very easy, and the          performance is very stable. It is adequate for not only engineering plastics with high melting temperature          such as polycarbonate, fluoroplastic, and nylon, but also the plastics with low melting temperature such as        polyethylene, polypropylene, polystyrene, ABS resin and acetaldehyde resin. It is widely used in plastic            production and petrochemical industry, and also in related institutions, research units and commodity                inspection department.
