Technical Description Model 321 / 322 / 343

Product catalog summary

Overview: This document provides technical specifications and procedures for Dip Viscosity Cups, Models 321, 322, and 343, used for rapid determination of fluid viscosity in various industries such as paint, varnish, and foodstuff.

Purpose and Application: The viscosity cups are designed to measure the efflux time of a 100 ml fluid sample through a specified orifice diameter. The test is conducted by immersing the cup in the fluid, lifting it out, and timing the efflux until the orifice is visible. This method is suitable for workshop environments.

Measuring Principle: Viscosity is determined by the efflux time of the fluid from the cup, measured with a stopwatch. The efflux time correlates with the viscosity of the fluid.

Model Specifications:

Model 321: Equivalent to DIN 53 211, available in nozzle diameters from 2 mm to 8 mm, covering viscosity ranges from 10 to 5,000 mm²/s. Suitable for efflux times between 20 - 200 seconds.
Model 322: Equivalent to EN ISO 2431, available in nozzle diameters from 3 mm to 6 mm, covering viscosity ranges from 10 to 680 mm²/s. Suitable for efflux times between 30 - 100 seconds.
Model 343: In accordance with ASTM D 4212, available in nozzle numbers from 1 to 5, covering viscosity ranges from 5 to 1,800 mm²/s. Suitable for efflux times between 20 - 80 seconds.

Additional Information: A complete set with five exchangeable cups and a handle is available in a carrying case.

Technical Description Model 321 / 322 / 343-2

Rapid determination of the viscosity of any type of fluid, as for instance paint, varnish, wet enamel, photogravure ink, dye and lacquer for leather, oil, fat, foodstuff etc. Particularly suitable in the workshop. The viscosity of a substance to be determined is expressed as the efflux time of the measured volume (100 ml) out of a cup through an orifice of specified diameter. The efflux time is measured with a stop-watch. The cup is totally immersed into and completely filled with the substance to be measured. It is then lifted out quickly, and simultaneously the stopwatch is started. The time...
