Overview
The FANGRUI NDJ-5S digital Viscometer adopts microcomputer drive technology, imported stepper motor and LCD backlight display. It has program setting and automatic control functions, which can realize smooth Rotation speed, good accuracy, easy operation, automatic scanning and error alarm. The screen directly displays information such as viscosity, Rotation speed, rotor number, percentile torque, maximum viscosity of range and liquid temperature. The instrument uses standard silicone oil for full scale and Linearity correction through PC interface to ensure high sensitivity, High Accuracy and High Repeatability, and the data is accurate and reliable. The absolute viscosity of Newtonian liquids or the apparent viscosity of non-Newtonian liquids can be determined, and the rheological performance of non-Newtonian liquids can be analyzed with software.

9. Optional data processing software can record the change of viscosity with time, Rotation speed, rotor or temperature in real time, and analyze the rheological characteristics of non-Newtonian liquids.
Principle
The FANGRUI NDJ-5S digital Viscometer is based on microcomputer drive technology and stepper motor control, and automatically adjusts the Rotation speed through the setting program to measure the viscosity of the liquid. The instrument uses the torque generated by the rotor when swirling/spinning in the liquid, combined with liquid crystal display technology, to directly output information such as viscosity, Rotation speed, rotor number, etc. Measurement accuracy and Repeatability are ensured through the PC interface for standard silicone oil correction, which can be adapted to the viscosity determination of Newtonian and non-Newtonian liquids.
Applications
Oil, paints, Coatings, Stock, Spinning & weaving, Food, Adhesive, Cosmetics and other fluids, semi-fluid production industries and R & D institutions
