Portable Field Viscometer: PDVdi-120

A New Instrument for the Rapid and Accurate Determination of the Viscous Properties of Newtonian and Non-Newtonian Fluids Including De-/Anti-icing Fluids

The PDVdi-120 Portable Field Viscometer is a revolutionary, portable, efficient, alternatives to larger full-featured laboratory viscometers.  The PDVdi-120 is simple to use, accurate, low-cost, compact, and lightweight field viscometer that can be taken anywhere to measure the viscosity of Newtonian and non-Newtonian fluids. The PDVdi-120  combines economy, ease of operation, accuracy, reliability, and versatility. High quality of instrument guarantees reliable performance for a long life. 

The new PDVdi-120 Portable Field Viscometer consists of a viscometer main body with a reusable syringe (tube) and a falling needle attached to an extension bar with two markings. The viscosity of the sample is determined by measuring the falling time of a needle through a predetermined distance (between two markings on the extension bar attached to the needle) within the fluids held in the reusable syringe. The falling time can be measured manually by a stopwatch. The viscometer includes a viscometer main body with two reusable syringes, a falling needle, a stopwatch, a digital thermometer, an instruction manual and a carrying case.
