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.
