MI-3

Our semi-automatic melt index tester with fix installed measuring weights

ASTM D1238
ASTM D3364
ISO 1133

MI-3熔融指数测试仪(塑性计)有一个集成全套砝码仓，带有电动升降单元并可手动进行砝码选择。

由于采用了高精度的位移传感器，即使非常低或非常高的MFR/MVR值也可以准确的记录下来。在测试砝码导杆上的外部活塞导向，使得即使高粘度材料也有很高的重复性。可更换的测试通道，可旋转的测试膛便于加料和清理。

设备使得用户在质量控制和进货检验上，依照标准 ISO 1133方法B以及ASTM D1238方法B自动测量MFR或者MVR成为可能。选配的切割单元,可以使测试按照ISO 1133方法A和ASTM D1238方法A计算。通过特殊的口模，测试也可以按照标准ASTM D1238 方法C（“半口模”）或者ASTM D3364

除了根据ASTM和ISO的标准MFR和MVR测量，GOTTFERT熔指仪有各种附加组件，提供额外的功能。

In addition to the standardized MFR and MVR measurements according to ASTM and ISO, the MI-3 offers a variety of add-ons that create real added value for materials testing. Trust in proven GÖTTFERT quality for maximum precision in material analysis.

Add-ons for advanced measurements

Our modular add-ons also offer an extended option for characterizing materials.

miCONNECT

Our miCONNECT software is a browser-based platform for workstation-independent management and analysis of measurement data, which can be used without installation.

MOISTURE MEASUREMENT INSTRUMENT

The residual moisture has a considerable influence on the measurement result for certain test materials. Therefore, it is recommended to dry test materials before a IV measurement and to determine the residual moisture.

附加设备

GÖTTFERT熔融指数仪可以有多种选配单元。此外，我们也提供一些附加设备，可以用来拓展设备功能。比如如下附加设备：

直连实验室天平，可用于熔体密度测量

DIE SWELL

The measuring head is mounted below the die. The measurement can be carried out parallel to a viscosity measurement.

Determination of the dynamic and static die swell
Evaluation of a die swell profile (BASELL method)
Swivel arm with continuous height adjustment
Laser measuring head available in various resolutions
Optional with automatic melt cutting device
Optional: acquisition of two strings simultaneously
Application: Simulation of material swelling behaviour during extrusion
