Portable Field Viscometer enables in-field measurements.

Press Release Summary:




Used to determine viscous properties of Newtonian and Non-Newtonian fluids, PDVdi-120 consists of viscometer main body with reusable syringe and falling needle attached to extension bar with 2 markings. Absolute viscosity measurement can be made without instrument calibration, and multiple measurements can be performed with one sample. Conforming to SAE AIR 5704 and ASTM D 5478, instrument has 20–10,000 cP viscosity range (2–106 cP with accessories) with accuracy and repeatability of >2%.



Original Press Release:



Introducing the Portable Field Viscometer, Model PDVdi-120



A new instrument for rapid and accurate determination of the viscous properties of Newtonian & Non-Newtonian fluids including De-/Anti-icing Fluids



PDVdi-120 is a portable, efficient, alternative to larger full-featured laboratory viscometers.  The PDVdi-120 is a 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.



The PDVdi-120 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 viscometer main body with two reusable syringes, falling needle, stopwatch, digital thermometer, an instruction manual and carrying case.



Key features include: field viscosity test, measures absolute viscosity without instrument calibration, multiple measurements with single sample, easy cleaning and maintenance (reusable syringe and large needle), quick measurement with immediate results, conforms to SAE AIR 5704 and ASTM D 5478
