Ⅰ. Introduction
GD-2806H ASTM D36 Ring and Ball Softening Point Test Apparatus is designed and made as per the National Standard of People's Republic of China GB/T4507 "Test Method for Softening Point of Asphalt", and T0606 "Asphalt Softening Point Test (Ring and Ball Method)" in the Industry Standard of People's Republic of China JTJ052 Specification and Test Methods of Bitumen and Bituminous Mixture for Highway Engineering.
GD-2806H ASTM D36 Ring and Ball Softening Point Test Apparatus is suitable to determine the softening point of bituminous materials such as asphalt, coal pitch, and liquid asphalt, etc.
GD-2806H ASTM D36 Ring and Ball Softening Point Test Apparatus is the best choice of asphalt manufacture companies, highway and bridge construction companies and related colleges and research institutes.
This instrument adopts microcomputer to control the test. Automatically stir, linear heating, automatically get the result and automatically print the test result.
The beaker adopts high temperature resisting glass material. The sizes of steel ring and ball can meet test standards.
Small desktop structure. LCD display. Ligh touch panel. It can determine four samples at a time. Easy to use and results reliable.
