Viscosity Control System is designed for adjusting viscosity of ink or glue on printing industry. The operator only needs to set the right viscosity according to the products’ requirement. The pulse tester will automatically test the viscosity, and then the pneumatic double-diaphragm pump will circulate the ink or the glue. This Roto-gravure and Flexo Printing Viscosity Control System is safe and reliable device. Its automatic viscosity tracking system maintains viscosity and color consistency.
