No. 521 Semi Auto Melt Indexer, 4A (Semi-automated Melt Flow Indexer)

Features

• Equipped with an automated measurement unit, a series of operations from the start of measurement after sample loading to the end of measurement are performed automatically.
• Automatic mechanism of loading test weight and residue emptying reduce operator burden and ensure operation safety, and shortening work time.
• Preheating conditions (preheating time, piston holding position, and holding time) can be set arbitrarily to maintain a constant actual preheating time until measurement starts, enabling stable measurement.
• The furnace cylinder cleaning unit enables one touch cleaning of the furnace body by setting gauze Features.
