A New Instrument for the Rapid and Accurate Determination of the Viscous Properties of Newtonian and Non-Newtonian Fluids

The PDV-100 and PDVa-100 Portable/Disposable Viscometers are revolutionary, portable, efficient, alternatives to larger full-featured laboratory viscometers.  The PDV-100 and PDVa-100 are simple to use, accurate, low-cost, compact, and lightweight field viscometers that can be taken anywhere to measure the viscosity of Newtonian and non-Newtonian fluids. The PDV-100 and PDVa-100 combine economy, ease of operation, accuracy, reliability, and versatility. High quality of instrument guarantees reliable performance for a long life.  Small sample size and temperature control can be accommodated.

The PDV-100 and PDVa-100 Portable/Disposable Viscometers consist of a support stand and a disposable sample tube filled with the liquid of which the viscosity is to be determined. Viscosity of the sample can be determined by measuring the falling time of a controlled needle through a predetermined distance of the fluid held in the sample tube. The falling time is measured automatically (PDVa-100) or manually  by a stopwatch (PDV-100).


Key Features

  • Disposable Sample Tube (4.5ml)
    (can be reused up to 30 times)
  • Measures Absolute Viscosity without Instrument Calibration
  • Field Viscosity Test
  • Inexpensive Non-Newtonian Viscosity Measurements
  • Quick and Easy Viscosity Measurements
  • Inexpensive
  • Automatic Falling Time Measurements to 0.001 second (PDVa-100)



Also Available

Constant Temperature Heating Block 

for Model DV-100, PDV-100 and PDVa-100

  • A constant Temperature Heating Block can hold 9 sample tubes and allows the samples to  achieve temperature equilibrium before viscosity measurement
  • It will drastically reduce the measurement time of multiple samples
