  1. The host uses high-precision rotary encoders instead of optical gauge structure, improving sampling frequency and displacement accuracy to meet new standards.
  2. The furnace is made of high thermal conductivity purple copper, with an increased outer diameter for improved temperature uniformity.
  3. The upper and lower partitions are made of high polymer thermal insulation material for enhanced overall insulation performance. The specially designed pressure bar, cleaning rod, nozzle plug, and cleaning rod for nozzle are convenient and practical.
  4. The temperature controller adopts high-accuracy and stable Japanese Omron brand.
  5. It comes with a dedicated microcomputer controller for the melt flow index tester, enabling full control, data processing, and printing of test results.
  6. Equipped with an aluminum alloy weight box.
