1. Instrument Overview: This instrument is in accordance with the industry standards of the People's Republic of China JTJ 052-2000《 In the test procedures for asphalt and asphalt mixtures for highway engineering T 0625《 Designed and manufactured as required by the Buckeye Rotary Viscometer Test (Blockfield Viscometer Method)" and is suitable for measuring the absolute viscosity of Newtonian liquids and the apparent viscosity of non-Newtonian liquids. It can be widely used in the measurement of the viscosity of various fluids such as asphalt, hot melt adhesive, paraffin, polymers, etc.

2. Main technical characteristics
1. This instrument adopts advanced mechanical design technology, manufacturing technology and microcomputer control technology, accurate data acquisition, high measurement sensitivity, reliable test results, easy to use and elegant shape.
2．The monitor uses white backlight and high brightness LCD The display screen can directly display the sample's viscosity, rotor number, speed and other information, and the data display is clear.
3．The test results can be displayed in real time on the display screen or printed out through the printer. In addition, through this instrument RS232 The data communication port can also be connected to a personal computer.
