I.Product introduction:
1) DSHD-2806G Automatic 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.
2) DSHD-2806G Automatic Asphalt Softening Point Tester is
applied to determine the softening point of highway asphalt,
coal pitch, liquid asphalt and other types of asphalt, etc. It is
the best choice of asphalt manufacture companies, highway
and bridge construction companies, colleges and universities,
and scientific research institutes.
3) DHSD-2806G Automatic Asphalt Softening Point Tester adopts
computer for controlling, electron photo-electricity for measurement,
LCD for indication and Micro-printer for printing test data.The instrument
also has linear heating temperature, even stirring speed and it can
make test for two samples at the same time and determine softening
point of samples automatically.
4) DSHD-2806G Automatic Asphalt Softening Point Tester is
automatic, convenient and reliable, so it is an intelligent
instrument for measuring softening point of asphalt sample.
