VZ-246 viscometer with three interchangeable nozzles

Viscometer VZ-246 is designed for rapid determination of the conditional viscosity (time of flow) of paintwork materials or related products - Newtonian or close to it liquids in accordance with GOST 9070-75.

VZ-246 viscometer is a tank in the form of a funnel with three interchangeable nozzles. Metal funnel is made of anodized aluminum, volume 100 ml, and equipped with three interchangeable stainless steel nozzles with an inner diameter of the outlet hole Ø2, Ø4, Ø6 mm. The principle of operation of VZ-246 viscometer is based on determining the time of flow of a certain volume of the tested liquid through the nozzle opening.
