儀器簡介：

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.
