Brookfield Rotational Viscometer (NDJ-1/B/C/D/E/F)

I. Summary
The NDJ-1F Brookfield rotation viscometer is designed and made according to the requirement of the T0625  in the JTJ 052  of the communication industry standard of the People Republic of China. The instrument is the upgraded product of the NDJ-1B and NDJ-1C Brookfield rotation viscometers in our company. It is suitable to determine the absolute viscosity of the Newton liquids and the apparent viscosity of the non-Newton liquids.
The instrument adopts the advanced machine design technology, manufacture techniques and microcomputer technology to control the temperature, collect and process the data. The display screen is a white background light, ultra bright LCD screen. The instrument also equips a pin micro-printer for output. The measurement can be displayed by the display screen in real time and plotted out through the printer. In addition, the instrument can connect to the PC through the RS232 communication interface.
The instrument has the characteristics of high measure sensitivity, reliable results and beautiful model, as well as convenience to operate. It is widely used to determine the viscosity of various liquids such as asphalt, hot sol, paraffin, high polymer and so on.
