AMETEK Brookfield FAST systems have a rugged design with non-moving parts. Designed to perform daily, maintenance-free, under the extreme demands of printing, coating and gluing operations. Using a high-frequency micro-rotating core that is immune to press vibration, this worry-free system can measure and control the viscosity of inks, coatings and adhesives from start to finish. Operators are free to handle other press issues.
