An automatic viscometer is a particular instrument for assessing how viscous a liquid is. This is called viscosity. The way we do this measurement is described in the ASTM D445. It is very necessary to use an automatic viscometer in accordance Automatic Volumetric DV17 with this standard. It enables industries, such as oil and food, to ensure that their products are just so. Liquids of the wrong texture can clog a machine, or ruin food. At ZONWON we offer high-quality viscometers that adhere to these guidelines, guaranteeing accurate and reliable measurements
