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).
