NDJ-5A/5S/8S/9S Digital Rotational Viscometer is an upgraded product of Digital Rotational Viscometer.
The instrument adopts reliable mechanical design technology, manufacturing process and microcomputer control technology, and the data acquisition is stable.
The display adopts a high-resolution 3.5-inch IPS display, the data display is intuitive, and the color screen can be directly displayed and stickydegrees, speed, temperature, percentage torque, rotor number, and the maximum number of the selected rotor number that can be measured at the current speedHigh viscosity.
The instrument has high measurement sensitivity and reliable test results, and is used to measure the absolute viscosity of Newtonian liquidsPrecision instruments for the apparent relative viscosity of non-Newtonian liquids.
It is widely used in grease, paint, plastic, medicine, food, coating, glue, adhesive, resin, chemical raw materialsViscosity measurement of various fluids such as materials.
