Purpose:
The instrument is designed and made as per the National Standard GB/T4507 "Test Methods for Softening Point of Petroleum Asphalt", and T0606 "Asphalt Softening Point Test (Ring and Ball Methods) in the Industry Standard JTJ052 Specification and Test Methods of Bitumen and Bituminous Mixture for Highway Engineering. It is suitable to determine softening point of petroleum asphalt, coal pitch, liquid petroleum asphalt, and other asphalts. It is the desired products for asphalt manufacturing companies, highway and bridge construction companies, colleges and universities, and scientific research institutes.
Computer control; linearity heating; automatic stirring. The test data is accurate and reliable. It can show test data automatically after a test. It is in accord with the National Standard GB/T4507.
