Overview
The Rotational Viscometer DV-79 is a precision instrument for the measurement of absolute viscosity of various Newtonian liquids and apparent viscosity of non-Newtonian liquids. When used with a specific rotor, the rheology of non-Newtonian liquids can also be determined. It has the advantages of convenient use, stable performance, simple maintenance, etc. It is suitable for the measurement of various oils, paints, inks, coatings, plastics, Stock, rubber, emulsion, detergent, Resin, condensed milk, cream, and cosmetics and other fluids. It is Spinning & weaving, chemical industry, petroleum, electromechanical, food, light industry, construction, and other industries as well as Universities & colleges, R & D institutions, military departments, laboratories, analysis rooms.
Features
1. Full Digital Viscometer
2, single turn multiple sampling
3. High subdivision drive stepper motor swirl/spin, Rotation speed is accurate and stable, AC voltage Frequency change does not affect the measurement viscosity accuracy
4. For thixotropic non-Newtonian liquids, the timing function of the instrument can ensure good conformity data
5, LCD liquid crystal with blue backlight function, direct display viscosity, Rotation speed, percentile torque, rotor at the current Rotation speed measurable maximum viscosity value
6. Overcome the shortcomings of NDJ-79 reading inconvenience, low Accuracy and poor stability
7. Simple and convenient operation. Rotation speed switching does not require manual installation of reducer
8. Before the instrument leaves the factory, the full-scale computer automatically calibrates it
Principle
DV-79 type Rotational Viscometer drives the rotor to swirl/spin in the liquid through a high subdivision drive stepper motor, and measures the resistance of the liquid to the rotor to determine the viscosity value. The instrument adopts single-turn multiple sampling technology to ensure the accuracy and conformity of the measurement data.
Applications
Spinning & weaving, chemical industry, petroleum, electromechanical, food, light industry, construction, Universities & colleges, R & D institutions, military industry
