Product Description

NDJ-1F Brookfield Rotational Viscometer

Product introduction：

Brookfield rotational viscometer is designed and made according to the requirement of the ASTM D 789, ASTM D 4878 and T0625 “Asphalt Brookfield Rotation Viscosity Test (Brookfield Viscometer Method)” in the Industry Standard of People’s Republic of China JTJ052 Specifications and Test Methods of Bitumen and Bituminous Mixtures for Highway Engineering. It is suitable to determine the absolute viscosity of the Newtonian liquids and the apparent viscosity of the non-Newtonian liquids. Brookfield rotational viscometer adopts the advanced mechanical design technology, manufacturing techniques and microcomputer technology for temperature control, data collection, and data processing. It takes a white background light, ultra bright LCD screen as display screen. The instrument also equips a pin type micro-printer for data output. The measurement data can be shown on the display screen in real time and printed out through the printer. In addition, the instrument can connect to the PC through the RS232 communication interface. Brookfield rotational viscometer has the characteristics of high measurement sensitivity, reliable results and delicate shape, as well as convenience to be operated. It can be widely used to determine the viscosity of various liquids such as asphalt, hot sol, paraffin, high polymer and so on.
