NDJ-1C Brinell rotational viscometerDetailed product description：

1、 Instrument Overview
The NDJ-1C Brinell Rotational Viscometer is designed and manufactured in accordance with the requirements of T0625 "Asphalt Brinell Rotational Viscosity Test (Brookfield Viscometer Method)" in the industry standard JTJ052 "Test Code for Asphalt and Asphalt Mixtures in Highway Engineering" of the People's Republic of China. It is suitable for measuring the absolute viscosity of Newtonian liquids and the apparent viscosity of non Newtonian liquids, and can be widely used for measuring the viscosity of various fluids such as asphalt, hot melt adhesive, paraffin, and high polymers.

2、 Main technical features
1. This instrument adopts advanced mechanical design technology, manufacturing process, and microcomputer control technology, with accurate data acquisition, high measurement sensitivity, reliable test results, easy operation, and beautiful appearance.
2. The monitor adopts a white backlight and high brightness LCD display screen, which can directly display the viscosity, rotor number, speed and other information of the sample, with clear data display.
3. The test results can be displayed in real-time on the screen or printed out through a printer. In addition, through the RS232 data communication port of this instrument, it can also be connected to a personal computer.
