GD-2801F Low Temperature Penetrometer/Asphalt Needle Penetration Testing/Penetrometer of Bitumen

GD-2801F Low Temperature Penetrometer/Asphalt Needle Penetration Testing/Penetrometer of Bitumen

Usage:

The instrument is designed and made as per the National Standard GB/T4509 "Test Methods for Needle Penetration of Petroleum Asphalt", and T0604 "Asphalt Needle Penetration Test" in the Industry Standard JTJ052 Specification and Test Methods of Bitumen and Bituminous Mixture for Highway Engineering. It is suitable to determine needle penetration of petroleum asphalt and asphalt. It can also be used for solid granule, powder, colloid, and other materials test, and cream, glycine, butter, fermentation, and other food inspection. It can be widely used in the food, highway construction, and other industries.
