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.
Key Features
- Unique micro rotational sensor
- No moving parts, no maintenance
- Unaffected by external vibration
- Flexible vertical or horizontal installation
- True temperature readings to 200°C
- Maintains correct color throughout the process
- Compact: only 8.5 inches tall
- Worldwide support

The STT-100 In-Line Viscometer is designed to provide years of trouble-free service in closed loop systems which require constant monitoring and associated control of product viscosity. This instrument is 3A approved and has been used successfully in many food applications.
Key Features
- Conforms to 3A sanitary conditions and has clean-in-place (CIP) design
- Continuous measurement eliminates need for “Grab” sampling and allows for prediction and constant control of final product properties
- Concentric cylinder geometry (Couette type) provides viscosity measurments at defined shear conditions
- Defined shear means agreement with Brookfield Laboratory measurements at equivalent shear rates
- Constant or variable speed motors available
- 4-20 mA output signal provides a variety of display and control capabilities
- Capable of a wide range of pressures, temperatures, viscosities, flow and shear rates
- Measurement “Zone” is protected from main flow, allowing accurate, repeatable measurement under variable conditions
- Mounts in-line supported by connections: Available in 3″ or 4″ pipeline connections; sanitary, threaded or flanged
- Easy to check and maintain calibration
