Rotational Viscometer EZL-RV312

EziLab offers the Rotational Viscometer EZL-RV312, a viscosity meter that reads from 1 to 2,000,000 mPa·s within 5% on Newtonian liquids. Rotor speeds run from 0.3 to 60 rpm, and four spindles cover thin liquids through heavy pastes. A built-in temperature sensor logs sample temperature with each reading, while a bubble level and adjustable feet keep the spindle vertical. The 2 kg body fits a 300 by 300 mm bench space and works in rooms from 5°C to 35°C. Choosing a spindle and speed pair lets one lab viscometer move from water-thin inks to stiff greases without a second instrument. Recording temperature beside each value matters because viscosity shifts sharply as samples warm or cool, so batch comparisons stay fair. Low 0.3 rpm speeds suit thick, shear-sensitive materials, while 60 rpm suits thinner fluids. Paint, lacquer, and ink producers check batch viscosity before filling, while adhesive and plastics makers confirm flow for coating and molding lines. Grease blenders verify consistency grades, cosmetic labs test creams and lotions, and food plants measure sauces and liquid products. Research groups use this rotational viscometer for routine viscosity measurement and new formulation studies. Greases, creams, and paints rarely behave as Newtonian liquids, so the 5% figure applies mainly to thin fluids; write the spindle and speed into your method so results stay comparable, then compare the Laboratory Viscometer category and Rotational Viscometer range.
