SYD-2806H Automatic Asphalt Softening Point Tester

 I. Summary

　The instrument is designed and made as per the National Standard of People’s Republic of China GB/T4507 “Test Method for Softening Point of Asphalt”, and T0606 “Asphalt Softening Point Test (Ring and Ball Method)” in the Industry Standard of People’s Republic of China JTJ052 Specification and Test Methods of Bitumen and Bituminous Mixture for Highway Engineering. It is suitable to determine the softening point of bituminous materials such as asphalt, coal pitch, and liquid asphalt, etc. It is the best choice of asphalt manufacture companies, highway and bridge construction companies and related colleges and research institutes.
It adopts computer controlling technology, electron photo-electricity measurement technology, LCD and micro-printer, and has the characteristics of linear heating temperature, uniform stirring speed, simultaneous four samples determination, and automatic softening point detection, so it is an automatic, convenient, reliable and intelligent instrument for softening point determination. It is the best choice of asphalt manufacturing companies, highway and bridge construction companies, college and universities, and scientific institutes.
