TBT-2801C Penetrometer
Summary
The instrument is designed and made as per the national standard of People's Republic of China GB/T 4509-1998/2010 Standard Test Methods for Penetration of Bitumen , GB/T269 Standard Test Methods for Cone Penetration of Lubricating Grease and Petrolatum and ASTM D217 Standard Test Methods for Cone Penetration of Lubricating Grease as well as T0604-2011 Bitumen Penetration Test in the industrial standard of People's Republic of China JTG E20-2011 Specifications and Test Methods of Bitumen and Bituminous Mixture for Highway Engineering. It is suitable for the asphalt penetration test and grease (or oil fat) cone into the degree of testing. The instrument can also be used for solid granule, powder, colloid, frozen materials such as body, and cheese, sugar, butter, wheat the spray, cream, fermentation and other food raw material inspection, in the food industry, transportation, highway engineering and other industries can be widely used.
