Automatic Asphalt Softening Point Tester

Purpose:

The instrument is designed and made as per ASTM D36 Standard Test Method for Softening of Bitumen (Ring-and-Ball Apparatus). It is suitable to determine softening point of petroleum asphalt, coal pitch, liquid petroleum asphalt, and various asphalts. It can be widely used for asphalt manufacturing companies, highway and bridge construction companies, relative colleges and universities, and scientific research institutes.
