Asphalt Digital Rotational Viscometer with bigger measuring range
Description
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.
The instrument has the characteristics of high measurement sensitivity, reliable results and beautiful model, as well as convenience to be operated. It is suitable to determine the absolute viscosity of the Newton liquids and the apparent viscosity of non-Newtonian liquids. It can be widely used to determine the viscosity of various liquid such as greases, oil paints, plastic, pharmaceuticals, dopes, adhesives, and detergents, etc.
Features
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.
