XNR 400C

Touch Screen Color Display Melt Flow Indexer
This type of Melt Flow Indexer is a new and affordable tabletop instrument that tests the melt mass-flow rate (MFR) and melt volume-flow rate (MVR) of a wide range of thermoplastic raw materials, in the form of granules, strips of film etc. This test method is particularly useful for quality control tests on thermoplastics. MVR will be found particularly useful when comparing materials of different filler content and when comparing filled with unfilled thermoplastics.

The MFR can be determined from MVR measurements provided the melt density at the test temperature and pressure is known.Test results can be converting automatically, with the function of Melt Density Test. The clear multi-line Touch screen allows fast, accurate input of test parameters and providing continuous display of setting during testing, printing the test result by a micro-printer. XNR 400C is design with the additional function of automatic weight loading.

The tester is far superior to all national and international standards of Melt Flow Rates requirements; including ISO1133, ASTM D1238, BS2782 and GB/T 3682 method A & B.


  • The built-in microprocessor maintains temperature control to within ± 0.5℃, with rapid ram-up to the set point.
  • Extruded material is automatically cut off by the built-in scraper mechanism at preset intervals, controllable to ± 0.1second.
  • Using PT100 Temperature Sensor

Two languages are provided: English and Chinese. XNR-400C Software has the functions of setting parameters, constant temperature control, cutting sample, calibration, setting test time, displaying test datum & result, calculating melt density, as well as checking & printing test datum. Password verifies is necessary for some main operations in case of mishandled.
