GD-2806G Automatic Ring and Ball Softening Point Apparatus by ASTM
The instrument conforms to ASTM D36 Standard Test Method for
Softening Point of Bitumen (Ring-and-Ball Apparatus)
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
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.
It is an automatic, convenient, reliable and intelligent instrument
for softening point determination.
