Power / connected load	Approx. 500–1200 W connected load for preliminary planning.
Overall instrument dimensions	Approx. 550 × 450 × 800 mm (W × D × H).
Instrument weight	Approx. 40–70 kg net.
Gross / shipping weight	Approx. 69–112.5 kg gross; estimated packing allowance.
Interfaces	USB communication port is available as standard.
Lab requirements	Suitable ventilation / process exhaust; external fan and duct loads are excluded from this preliminary estimate.

Dimension order and approximate values are stated in each row. Packaging data are separate from instrument dimensions and net mass. Approx. rows are preliminary engineering estimates based on comparable equipment and function/capacity; they are not verified manufacturing measurements or standard requirements. Installation and shipment are finalised against the approved drawing and nameplate. Estimate scope: base product / one unit; external computer, bench and auxiliary plant excluded.

Specifications, dimensions, and power requirements are approximate and subject to change without prior notice for continuous design improvements.

Product technical specifications and images may vary according to manufacturing conditions and applicable standards.

Test and configuration

Measured output / function: Melt mass-flow rate MFR (g/10 min)
Parameters selected for the method: Temperature, total load, die and cut interval
Verification points: Temperature profile, loads, timer and weighing

Listed methods are application references. Suitability is established by assessing the selected hardware, current method and calibration together.

Test parameters for the reviewed method

Values belong to the stated source edition. Test recipe, fixture and delivered instrument configuration are selected together.

ISO 1133-1:2022 · 5.1.2-5.1.5, Table 2

Cylinder bore 9.550 ± 0.007 mm; piston head diameter 9.474 ± 0.007 mm and length 6.35 ± 0.10 mm; standard die length 8.000 ± 0.025 mm and bore 2.095 ± 0.005 mm. Temperature setting step no greater than 0.1 °C; setting resolution is not temperature accuracy.

ASTM D1238-10 · 5.4, 5.6, 5.7.6

Combined piston and load mass within ±0.5% of the selected load. Procedure A timer accuracy 0.1 s; extrudate balance capable of weighing to 0.001 g. Automatic piston-travel measurement requires the corresponding procedure and hardware.

Control and recording specification

The following are method-specific software/recording requirements; delivered software modules are defined by the order scope.

Method code and edition, specimen ID, operator and selected test parameters are linked to the record.
MFR = 600 × extrudate mass(g) / cut interval(s); MVR requires a separate displacement measurement.
Raw measurements, units, valid/invalid test flags and the reported result remain traceable.
Calculations are checked against known inputs and an independent calculation; sensor channels are checked against calibration values.

Built-in automatic weighing and an MVR displacement system are not verified in the available source.
