GDJ-1C Rotational Viscometer
Ⅰ. Purpose
Brookfield Rotational Viscometer(GDJ-1C) is designed and made as per T0625 “Asphalt Rotation Viscosity Test (Brookfield Viscometer Methods)” in the Industry Standard JTJ052 Specification and Test Methods of Bitumen and Bituminous Mixture for Highway Engineering.
Brookfield Rotational Viscometer is suitable to determine absolute viscosity of Newton liquids and apparent viscosity of non-Newton liquids. It is sensitive, reliable, convenient, beautiful, and it only needs little sample. It can be widely used to determine viscosity of asphalt, hot melt adhesive, paraffin, high polymer, and other liquids.
