Pellets, flake, or powdered  product are automatically sampled and from a process and transported  to a small extruder at or away from the process. Continuous sampling of product Away from the process. Does not interfere with manufacturing. Eliminates the need for “hazardous location” design.           The extruder melts and transports the product to one or more test instruments. Multiple test capability - MFI (Viscosity), composition, contamination, density Fast response. Tested as “the customer” will see it.     Practical multiple on-line analyses “Out of the way!” - Can be installed on the  manufacturing floor or in the QA lab. Isolated from hazardous environments. Fast response. Simple calibration.  Eliminates sampling problems. Provides statistically representative sample. Product tested “as your customer will see it!”
