SYD-2801I Needle Penetration Automatic TesterDetailed product description：

The SYD-2801I Needle Penetration Automatic Tester is designed and manufactured according to the requirements specified in the Chinese standard GB/T 4509 "Determination of Needle Penetration of Petroleum Asphalt" and the Chinese industry standard JTJ052-2000 "Test Code for Asphalt and Asphalt Mixtures in Highway Engineering", specifically T0604 "Asphalt Needle Penetration Test". It is suitable for measuring the needle penetration of road petroleum asphalt, modified asphalt, as well as the needle penetration of residual liquid petroleum asphalt or emulsified asphalt after evaporation; After purchasing selected accessories, the cone penetration of substances such as paraffin and lubricating grease can be measured. This instrument can also be used for the inspection of solid particles, powders, colloids, frozen bodies and other materials, as well as food raw materials such as cheese, sugar gum, butter, malt extract, cream, fermented bodies, etc. It can be widely used in the food industry, transportation and highway engineering, and other industrial sectors.
