MFI-1221 Melt Flow Indexer

It is an 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 etc. The tester is far superior to all national and international standards of Melt Flow Rates requirements. This product has been CE certificated.


  • LCD display the test result, l micro printer may print out the MVR result.
  • With the functions of test temperature display, upper limit protection and sound notification. Thanks to the advanced PID controller and high resolution sample circuit, the temperature can ramp up to the set point with slight overshoot and high accuracy in stability.
