SYD-0621C High and Low Temperature Asphalt Standard Viscometer

Product Information

This instrument is designed and manufactured in accordance with the requirements specified in T0621 "Asphalt Standard Degree Test" of the transportation industry standard "JTG3410-2025 Test Regulations for Asphalt and Asphalt Mixtures in Highway Engineering" of the People's Republic of China. It is suitable for measuring the viscosity of liquid petroleum asphalt, coal tar pitch, emulsified asphalt and other flowing states according to the methods specified in T0621 standard. The viscosity of asphalt is the time required for 50 milliliters of asphalt material to flow out of a specified flow hole at a specified temperature, expressed in seconds.

The instrument comes standard with an external low-temperature circulating water bath, which can achieve viscosity testing at 5-70 ℃. The relevant content of low-temperature water bath can be found in the second part of this article.
