FAST Viscometer

The Brookfield FAST system has a rugged design with non-moving parts. It has been designed to perform day after day under the extreme demands in printing, coating and adhesive operations – with no maintenance. Utilizing a high frequency, micro-rotational core, which is unaffected by press vibration, this worry free system can measure and control the viscosity of your inks, coatings and adhesives from start to finish…allowing the operators to handle other press concerns.
