VISCOSIMENTO AUTOMATICO

A viscometer comprises a liquid feeding conduit opening into a measuring chamber and a capillary liquid outlet conduit connected to said chamber, pressure-sensitive means associated with said chamber for sensing the pressure variations in the latter, converting means for converting the pressure variations sensed by said pressure sensitive means into measurable and displayable quantities of value, said feeding and capillary conduits and said pressure-sensitive means being enclosed in a metallic block arranged in a heat-insulated space which includes heating means for heating said block, said heating means being adapted to maintain the temperature of said block at an adjustable predetermined value.
