GD-2806G Automatic Machine for Testin Asphalt Softening Point 

• 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 Asphalt", and T0606 "Asphalt Softening Point Test (Ring and Ball Methods)" in the Industry Standard of People's Republic of China. 

• It is suitable 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. 

• It adopts computer for controlling, electron photo-electricity for measurement, LCD for indication and Micro-printer for printing test data.

•  It also has the characteristics of 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. 

• It is automatic, convenient and reliable, so it is an intelligent instrument for measuring softening point of asphalt sample.
