EziLab Rotational Viscometer EZL-RV311 measures viscosity of Newtonian fluids across paints, inks, adhesives, food products, cosmetics, and research laboratory applications. Measurement range spans 1 to 1×10⁵ mPa·s with ±5% tolerance, while rotor speed ranges from 6 to 60 rpm for flexible testing conditions. Compact structure allows easy laboratory placement, and stable operation ensures repeatable rotary viscometer measurements across extended testing sessions. Simple controls allow straightforward operation without complex setup or calibration procedures. EziLab's Lab Equipment and laboratory viscometers carry the complete rotary viscometer and Newtonian fluid testing range for laboratory and industrial use.
