Introduction
Flexible, compatible, systematic:
Step by step from the simplest starter model mi2.1 up to the top equipped half-automated mi2.3.
The Evolution of the melt index measurement!
The mi2 melt indexer series can carry out measurements according to ISO 1133 and ASTM D1238, procedures B, as well as ISO 1133 and ASTM D1238 procedure C for the "Half Height / Half Diameter" standard and ASTM D1238 procedure D (optional, only available for device type mi2.2) for the FRR test (Flow Rate Ratio) and ASTM D 3364. Also the manual procedure A is possible to perform.

The technical highlights
 Brilliant 14.48 cm (5.7") Color-VGA Touch screen display for the operation, program control and display of the measurement results
 Ergonomic compact housing
 High-precision timer with a resolution better than 0.001 s
 Temperature control algorithm, resolution 0 to 320°C: 0.01°C, 320 to 500°C: 0.1°C
 High-resolution position transducer to measure volume output

Additional features for all mi2 device types:
 Single weight mode for tests with one weight
 Free selectable test range from 50 to 0 mm before the die
 Storage of up to 500 parameter sets with 3000 measurements for each parameter set
 Capillary/die quick-release and locking mechanism
 Base weight 0.325 kg
 Electrically heated test chamber for high precision and stability of the test barrel temperature
 5 Calibration settings for set temperatures with dedicated parameter files
 Manual and timer-programmable on/off override switch for the heaters
 Built-in USB-connection (Data Stick) for data back-up
 Serial connection to communicate with the optional scale
 Ethernet-connection (LAN)
 Integrated Web-Server
 Wide range of optional accessories

The basic device mi2.1 consists of the following components:
Housing: Ergonomic compact housing for safe test and maintenance procedures. The 4 feet are adjustable in height, which facilitates leveling of the equipment
Test chamber: The insulated test chamber is heated with two heating circuits. The test barrel is easily accessible from top and below for cleaning
Test barrel: Diameter 9.55 mm
Capillary: Capillary, 2.095 mm diameter, 8 mm length, constructed from tungsten carbide and serial number engraved
Die quick release and locking mechanism: The capillary is held and released by the quick-locking mechanism, which works simply and fast. Thus the test channel can be cleaned user friendly
Test piston with test weight 0.325 kg: This test weight is affixed atop the ISO or ASTM specified piston. The assembly has a total weight of 0.325 kg. The test piston shaft has reference rings as reference marks for the ISO and ASTM standard measuring zones
Digital position transducer: High-resolution digital encoder to measure volume output
Color-VGA-Touch screen: For the input of parameters, for program control and for the display of results
Compact I/O-Module: For control and to receive input signals
Temperature Controller: The test chamber temperature is controlled by a special temperature control algorithm. The temperature set points are entered via the touch screen display. During the test, the temperatures are displayed on the screen with a 0.01 °C resolution
USB Connections: to communicate with a PC, or to connect to a data stick for data back-up in ASCII-Format
Ethernet-connection: LAN connection and communication with MFRView software or with a networkable printer.
Also for use as FTP or Web-Server
Serial Connection: Connection to a scale
