STT-100 Sanitary Viscometer

STT 201x583

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.



  • 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



  • Viscosity Range: 350 - 250,000 (cP/mPa·s)
  • Speeds: single speed: application specific
  • Input Power: 115 Vac: 50/60 Hz or 230 Vac: 50/60 Hz, 24 Vdc, 12 Vdc
  • Output: 4 - 20 mA



  • Standard design with flanged connections
  • Variable speed motor
  • Computer controlled variable speed viscometer
