FAST Viscometer

FAST System 201x583

The AMETEK 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.
