The new PDV-4.5Portable 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.
