QM280A Melt Flow Index Tester

The QM280A melt flow index tester measures the plastic melt flow rate (MFR, Method A): per the material condition table it applies a specified temperature and load and measures the mass extruded through the die in 10 minutes to evaluate material flowability.

Temperature range RT~350 °C, with a heat-resistant double-band heater and Micro-Blade auto cutting; test methods and condition tables are built in, and mass is calculated automatically to prevent human error.

Optional Method B MVR (melt volume-flow rate) uses a high-pulse-encoder high-precision distance sensor to automatically measure the volume change of high-flow resins.
