Features of VTA Pneumatic Viscosel
  • Convenient & Inexpensive: Viscosity measurement and control combined in one compact package that mounts easily to process equipment on the production floor. Operating method uses the well-accepted coaxial cylinder principle of viscosity measurement.
  • Responsive: The Viscosel®'s sensitive response and automatic operation assures continuous conditioning of fluid.
  • Measures In-line: Eliminates time constraints associated with viscosity analysis of grab samples in the laboratory; provides early detection and correction of in-process deviations from desired set points.
  • Quality Control: Decreases raw material and product waste; maintains control of desirable product qualities (coating thickness, ink printability, % solids, etc.)
  • Easy to clean: Only the measuring cylinder and sample chamber come in contact with the sample. They can be easily cleaned or - if necessary - replaced without re-calibration.
  • Easy to Change Range: Measuring cylinders hook on and off easily, without tools and without need to adjust the instrument.
  • Standard or Custom Mounting: Using the standard mount, the Viscosel® can be moved wherever and whenever required. Custom bracket, cart, and tank mounts are available
  • ±1% accuracy full scale: The Viscosel® is guaranteed to be accurate within ±1% of the range in use and reproducible to ±0.5% of full scale range.
  • Easy-to-read viscosity indication: The easily read set point mark and viscosity indicator are in parallel when the instrument is on control, making possible a quick visual check, even from a distance.
  • Safe pneumatic operation: The Viscosel® and its drive, the indicator/controller and the valve for solvent addition are all pneumatically operated, without complex electronic circuits.
  • Finely modulated control: The Viscosel® system offers on/off pneumatic control with 1% throttling action. Whether working with inks, coatings or lacquers, the instrument maintains constant viscosity by controlled solvent addition. The viscometer is also available as a transducer only.
