China Digital Display Rotational Viscometer

NDJ-1B Rotational Viscometer(Digital)
Summary
The instrument adopts advanced mechanical design technology, manufacture technique and microcomputer controlling technology. It can collect data accurately. Using white background light and ultra-bright LCD, it can show test data clearly. Equipped with a special printer interface, it can print out measurement data through a printer. It is used to determine absolute viscosity of Newtonian liquids and apparent viscosity of Non-Newton liquids. It is widely used to determine the viscosity of liquids such as greases, oil paints, plastics, pharmaceutics, coatings, adhesives, washing solvents, and other fluids.

I. 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.
4. Choose different models can have different ranges, for measuring different samples.
