Introduction

The instrument is designed and made as per ‘Asphalt Brookfield Rotational Viscosity Test (Brookfield Viscometer Method)’ in the Industry Standard 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.
