Digital Display Rotational Viscometer

RV-NDJ-79B Digital Display Rotational Viscometer

Product introduction

RV-NDJ-79B Digital Display Rotational Viscometer is the upgraded instrument of RV-NDJ-79 rotational viscometer. It can be used to determine absolute viscosity of Newtonian liquids and apparent viscosity of Non-Newtonian liquids.

It can be widely used to determine the viscosity of liquids such as greases, oil paints, plastics, pharmaceutics, coatings, adhesives, detergents and other fluids. The viscometer has the advantages of small volume, light weight, convenient and simple maintenance, durable and can rapidly and reliably measuring liquid viscosity and other characteristics.

Main technical features

1. The instrument adopts advanced mechanical design technology and manufacturing process, using micro-computer technology to control speed, collect data and process data. Accurate data acquisition, high sensitivity, reliable test results, easy to use, and good looking.

2. Display selection of white backlight, high brightness LCD display, can directly display the viscosity of the sample, the number of the rotor, speed and other information, data display clear.

3. The test data can show on the screen real time and also output by printer. In addition, the instrument can also connect with PC via RS232 communication port.
