The AST-100 is the world's most innovative means of viscosity control. The AST-100 is a versatile instrument that is excellent for customers who are looking for viscosity control (i.e. maintaining the viscosity of the product) in their process more than the measurement of an exact number (ex. 23.5cP). It is easy to install, cleans-in-place, and has no moving parts, so maintenance is minimal. With available options it is suitable for explosion-proof applications or 3A food-grade applications as well.
| Viscosity Range: | 2 - 3000 (cP or equivalent cup-seconds) |
| Temperature Range: | -20°C - +120°C |
| Repeatability/Stability: | ±1% of the Reading |
| Outputs: | 4 - 20 mA RS-232 RS-485 |
| Connections: | 1″ NPT inlet/outlet |
The new AST-300SY Single Station Viscosity Controller and AST-400SY Multi-Station Viscosity Controller are designed for use with Brookfield AST-100 Systems to accurately measure and control viscosity.
The AST-300SY Single Station Controller is designed for use with the Brookfield AST-100TSY as part of the viscosity control system to measure viscosity and temperature, interlock with other process devices, and accurately control the viscosity of your product in a variety of industrial applications.

The AST-400SY Multi-Station Controller is designed for use with up to ten Brookfield AST-100TSY viscosity control units as part of a multi-product viscosity control system. The system will measure viscosity and temperature, interlock with other process devices, and accurately control the viscosity of your products in a variety of industrial applications.
