Asphalt Tester by Ring And Ball

Description

I. Summary
　The instrument is designed and made as per the National Standard of Peoples Republic of China GB/T***7 Test Methods for Softening Point of Asphalt and T***6 Asphalt Softening Point Test (Ring and Ball Methods) in the Industry Standard of Peoples Republic of China JTJ**2 Specifications and Test Methods of Bitumen and Bituminous Mixtures for Highway Engineering. It is suitable to determine the softening point of asphalt, tar, liquid asphalt and other types of asphalt. It is the best choice of asphalt manufacturers, highway and bridge construction companies, college and universities, and research and development departments.
　It adopts microcomputer controlling technology, linear heating and automatic stirring working mode, it can determine two samples at the same time and it can show test results automatically. It is convenient, efficient, and reliable. It is the desired instrument for laboratory to determine the softening point of asphalt.
