AB This article describes the design and testing of alow-cost automatic rolling-ball viscometer. The device hasbeen manufactured from three-dimensional printed partsand conventional and affordable mechanical and electronic components. It is controlled by an Arduino MEGAwith a custom code that includes manual and automaticmeasuring modes. Both the type of viscometer and themodels used are, in principle, valid for Newtonian andpower-law fluids. However, measurement and calculationprocedures have been developed that also makes it possible to determine the viscosity of Herschel–Bulkley fluidsthat might exhibit a yield stress behaviour within the rangestudied. By these procedures, viscosity values have beenobtained for model fluids – Newtonian, power-law, andHerschel–Bulkley fluids – and compared to those obtainedwith a commercial rotational rheometer. The proposedsetup and measuring method have thus proven to providevery reasonably accurate viscosity values for a low-costdevice
