Product introduction: 1:DSHD-2801F Low Temperature Penetrometer is designed and developed 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. 2:DSHD-2801F Low Temperature Penetrometer is applied to determine needle penetration of petroleum asphalt and asphalt. The instrument can also be used for solid granule, powder, colloid, and other materials test, and cream, glycine, butter, fermentation, and other food inspection. The instrument can be widely used in the food, highway construction, and other industries. Technical parameters: 1.
