GM8804CD

GM8804CD Dual-hopper packaging controller

The packaging controller is the first dual-hopper packaging controller in the world, which offers a integrated and value adding solution for applications in which multiple hoppers are on a single scale. And It has the same high performance and key technologies while offering lower cost for us clients by controlling two hoppers with a single indicator.


  • CE compliant
  • 28 I/O control (12 inputs and 16 outputs)
  • Perfect balance between speed and precision with automatic three-speed feeding
  • Advanced free fall compensation algorithm for extremely precise result every time
  • Smart calibration without weight
  • 10 recipes can be stored for different weighing capacity
  • Patent pending two-layer advanced digital filtering algorithm
  • Setting batching numbers
  • Two serial communication ports to connect with computer, printer and/or a second display
