Description
Overview
GAOTek Digital Rotational Viscometer with heating the instrument is designed and made as per T0625 “Asphalt Rotational Viscosity Test (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.
Features
- Digital display for viscosity and temperature readings
- Built-in heating system for viscosity at different temperatures
- Wide viscosity range for versatile applications
- User-friendly interface with temperature control
- Suitable for research, quality control, and industrial use
