NDJ-8S | Digital Viscometer

The NDJ-8S Digital Viscometer is a laboratory and quality-control instrument used to measure the apparent viscosity of Newtonian and non-Newtonian liquids in production, formulation and research work. It is widely used in paints, coatings, inks, adhesives, grease, cosmetics, food products, pharmaceutical liquids, slurries, pulp, latex, and other semi-fluid materials. The NDJ-8S offers a wide viscosity measuring range from 1 mPa·s to 2,000,000 mPa·s, eight selectable speeds from 0.3 to 60 rpm, an LCD display, timing measurement, automatic scanning, an overflow alarm, and direct viscosity reading without manual calculation.

Pro Tip

For reliable viscosity results, control the sample temperature before testing and keep the torque value within the effective 15%–80% range. Viscosity changes strongly with temperature, so even a small variation can affect repeatability in paints, food liquids, coatings and pharmaceutical samples. Buy NDJ-8S Digital Viscometer from Kamadi Pakistan for laboratory viscosity testing and industrial quality control.

Buyer’s Selection Guide

Choose the NDJ-8S if you need a wide-range digital viscometer for low, medium and high-viscosity liquid testing. It is more suitable than basic 4-speed viscometers when your samples vary widely in viscosity or when you need slow-speed testing for thicker fluids. For samples below 15 mPa·s, select the optional No. 0 rotor with small sample adapter.
