The AST-100 is the world's most innovative means of viscosity control.

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.

Features

• No moving parts to wear, bind or contact process materials
• Simple Clean-In-Place design
• Rugged 316 SS construction
• Continuous, reliable 4-20 mA output
• Saves you money while increasing your production
• Easy installation
• Digital display
• Available in food-grade and explosion-proof designs
