I.Product introduction:

1) DSHD-2806E Asphalt Softening Point Tester is designed and

  developed as per the National Standard of People's Republic

  of China GB/T4507 "Test Methods for Softening Point of Asphalt"

  and T0606 "Asphalt Softening Point Test (Ring and Ball Methods)"

  In the Industry Standard of People's Republic of China JTJ052

  Specifications and Test Methods of Bitumen and Bituminous

  Mixtures for Highway Engineering.

2) DSHD-2806E Asphalt Softening Point Tester is applied to

  Determine the softening point of asphalt, tar, liquid asphalt and

  other types of asphalt. The instrument is the best choice of

  asphalt manufacturers, highway and bridge construction companies,    

  college and universities, and research and development departments.

3) DSHD-2806E Asphalt Softening Point Tester adopts microcomputer   

  controlling technology, linear heating and automatic stirring working

  mode. The instrument can determine two samples at the same time

  and show test results automatically. It is convenient, efficient, and

  reliable and is the desired instrument for laboratory to determine the

  softening point of asphalt.
