Product introduction:
The instrument is designed and made as per T0625 "Asphalt Brookfield Rotational Viscosity Test (Brookfield Viscometer Method)" in the Industry Standard of People's Republic of China JTJ052 Specification 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.
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. 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.
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.
Main technical specifications:
Measurement range 100 mPa·s~2×105 mPa·s (If you select the No.30 spindle, the measurement range can be extended to 4×105 mPa·s)
Spindle No.21, 27, 28 and 29 total 4 pieces of spindles (the No.30 spindle is optional)
Rotation speed 5RPM, 10 RPM, 20 RPM, and 50 RPM
Measurement error ±2% (F·S); (If you select the No.30 spindle, it will be ±3% (F·S)
Temperature control range 45 ºC~200 ºC
Temperature control accuracy ±0.1 ºC
Sample cylinder 20 ml
Power supply AC 220V±10%, 50 Hz
Ambient temperature 5 ºC~35 ºC (when the controlling temperature is close to ambient temperature, please run the air conditioner to let the ambient temperature be 5 ºC lower than the controlling temperature)
Relative humidity ≤80%

When purchase a Rotational Viscometer , you should know what samples you determine and viscosities of samples.
&    Instrument with a measurement range of 1 to 200 thousand (mPa.s) for low viscosity fuids.
Such as: latex, biological fluids, oils, paints, cosmetics, pharmaceuticals, hot paraffin, inks,and juices.
&    Instrument with a measurement range of 1to 2 minllion (mPa.s) for medium viscosity fluids.
Such as: paint,paper coating, paper pulp, starch, toothpaste, ceramic slurries, and cream-type materials.
&    Instrument with a measurement range of 2 to 10 million (mPa.s) for high viscosity fluids.
Such as: asphalt, chocolate, gelatin, ointment, peanut butter,tar.
