description

This instrument is engineered and manufactured in accordance with T0625 “Asphalt Brookfield Rotational Viscosity Test (Brookfield Viscometer Method)” specified in the People’s Republic of China Industry Standard JTJ052 Specification and Test Methods of Bitumen and Bituminous Mixture for Highway Engineering. It is suitable for determining the absolute viscosity of Newtonian liquids and the apparent viscosity of non-Newtonian liquids.

features

Test data can be displayed in real time on the integrated screen, printed via the built-in printer, or transmitted to a computer through the RS232 communication port for further analysis.

The instrument integrates advanced mechanical design and manufacturing techniques with microcomputer technology to enable precise temperature control, automated data collection, and streamlined data processing.

Featuring a backlit, ultra-bright LCD display and an integrated micro-printer, the device ensures clear readability and on-demand test report generation.

Users can select rotational speeds based on the measured liquid’s viscosity to meet diverse measurement range requirements.
