Melt Flow Index Tester melt mass-flow rate (MFR) and melt
volume-flow rate (MVR)
|1||Function||This type of melt flow indexer is a high precise melt testing
instrument for the measurement of melt flow rate (MFR)/(MI) or melt
volume rate (MVR) in quality control and research applications. The
testing result can distinguish the viscous flow performance of
thermoplastic material by the model MFI452 showing its advantage in
the following industries: factories, products quality testing
station, scientific and research institutes, and concerned
Comply with ISO1133, ASTM D1238, ASTM D3364, BS2782, DIN53735, JIS
K7210, or other similar standards.
|4||Operation||Operation button on the Control panel, easy to operate. The test
parameter can be shown on the LCD display.|
- Two digital display control panels with membrane covered buttons,
comfortable touching, intuitive operating and real-time data
- Test method (MFR/MVR) can be pre-selected by the control panel, and
test can be conducted automatically as preset program. And there is
a friendly prompt by hum to alarm the coming end of each test step
in the whole test process.
- The AL808 temperature control system is configured with two groups
of platinum resistor temperature transducers and one group of the
two is used as spare part which makes a high reliability. And the
PID algorithm is used to adjust the temperature and compensate the
influence of temperature caused by the environment or undulation of
power to ensure a good stability.
- Automatic cut-off device, driven by motor, small size, good
flexibility. It can carry out the automatic timing cut-off, jog
cut-off and manual cut-off as the need of the customers.
- Built-in micro-printer. When the Test is completed, the results
will be printed on scrip clearly only by pressing on the “Print”
- The displacement of the piston rod is exactly measured by the
- The piston rod and the filling canister are all made of nitriding
steel with high rigidity and strong corrosion resistance.
- A set of elaborately designed accessories to provide a convenient
operation and maintenance.
