coefficient of a coating can be measured and controlled in several ways.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">However, there is one instrument that excels beyond the others in terms of performance: it\u2019s the&nbsp;<strong><a href=\"https:\/\/www.samatools.it\/en\/product\/digital-rotary-viscometers-savisc162\/\">digital rotary viscometer.<\/a><\/strong><\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The digital rotary viscometer, like our SAVISC186 model,&nbsp;<strong>allows you to check the dynamic viscosity of the coating at a specific operating temperature.<\/strong><\/p>\n\n\n\n<p class=\"wp-block-paragraph\">This is important because<strong>&nbsp;temperature is one of the environmental aspects that can have the most impact on the viscosity of your coating.<\/strong><\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The process of measuring the dynamic viscosity with a digital rotary viscosimeter starts by pouring a sample of the coating into a container and placing the container so that the spindle of the viscometer is inside the coating.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">After that, the spindle rotates at a constant speed and the viscometer measures the torque value to determine the viscosity.<\/p>\n\n\n\n<figure class=\"wp-block-image size-large is-resized\"><img decoding=\"async\"

are digital rotary viscometers most commonly used for?<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Many industries depend on viscosity control and therefore use rotary viscometers.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Specifically,&nbsp;<strong>these types of tools are particularly useful when checking dynamic viscosity in non-Newtonian fluids.<\/strong><\/p>\n\n\n\n<p
