AST-300SY Specifications
The AST-300SY is designed for use with the Brookfield AST-100TSY system to control viscosity and temperature, interlock with other process devices, and accurately control fluid viscosity in a variety of industrial applications.
The AST-300SY is a precise, programmable controller with timed dosing intervals. Its intuitive screen layout allows for quick selection of setup and menu items. At a glance, set point and alarm status are displayed as are viscosity in cP, mPa•s, cSt or cup-seconds, current pH value and temperature in °C or °F.
