Determine absolute viscosity of Newtonian liquids and apparent viscosity of Non-Newtonian liquids

  • NDJ-1C
  • TBTSCIETECH

The instrument is designed and made as per T0625 “Asphalt Brookfield Rotational Viscosity Test (Brookfield Viscometer Method)”  and Test Methods of Bitumen and Bituminous Mixture for Highway Engineering.

It is suitable to determine absolute viscosity of Newtonian liquids and apparent viscosity of Non-Newtonian liquids.

1. The instrument adopts the advanced mechanical design technologies and manufacturing techniques, and uses microcomputer technologies for temperature control, data collection and data process. The display is a background light, ultra-brighten LCD.

2. It is also equipped with a micro-printer for printing. The test data can be shown on the LCD in real time or printed out through the printer. It can also connect to a computer through the RS232 communication port.

3. The instrument has characteristics of high measurement sensitivity, reliable measurement data, convenience, and good looking. It can be widely used to determine viscosity of asphalt, hot melt adhesive, paraffin, high polymer, and various fluids.
