SHUJU NDJ-5S Rotational Viscometer (Standard Model)

Product Highlights

The NDJ-5S color-screen rotational viscometer is an upgraded version of digital viscometers. It incorporates advanced mechanical design, manufacturing techniques, and microcomputer control technology to ensure stable data acquisition. The high-resolution 3.5-inch IPS display provides intuitive data visualization, showing viscosity, rotational speed, temperature, percentage torque, rotor number, and the maximum measurable viscosity for the selected rotor at the current speed. With high measurement sensitivity and reliable test results, this precision instrument is designed to measure the absolute viscosity of Newtonian liquids and the apparent relative viscosity of non-Newtonian liquids. It is widely used for viscosity measurement of various fluids, including oils, paints, plastics, pharmaceuticals, food, coatings, adhesives, resins, and chemical raw materials.
