Product Description
DSHD-2806F Automatic Asphalt Softening Point Tester
I. Purpose and scope
The instrument is designed and made as per the National Standard of People’s Republic of China GB/T4507 “Test Methods for Softening Point of Petroleum Asphalt”, and T0608 “Asphalt Softening Point Test (Ring and Ball Methods)” 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 softening point of petroleum asphalt, coal pitch, liquid petroleum asphalt, and various asphalts. It is the best instrument for asphalt manufacturing companies, highway and bridge construction companies, relative college and universities, and scientific research institutes.
Adopts microcomputer controlling, linear heating and automatic stirring mode, it can make tests for two samples at the same time. It can automatically show measurement results after test. It is convenient, efficient, and reliable. It is the best instrument used to determine softening point of petroleum asphalt in the asphalt inspection laboratory.
