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 fal领 time of a controlled needle through a predetermined distance of the fluid held in the sample tube. The fal领 time is measured automatically (PDVa-100) or manually by a stopwatch (PDV-100).
