The fully automatic softening point tester is used to determine the softening point of electrode paste, bitumen, polymer-modified bitumen, and other viscous materials. It evaluates the material’s thermal softening and flow properties, providing essential data for quality control, research, and construction applications.

Electrode Paste Softening Point Tester

Model:TDRD-7

I.Product Introduction

The new fully automatic softening point tester determines the softening point of viscous petroleum asphalt based on the ring and ball method.This instrument is suitable for determining the softening point of electrode paste,rubber,road petroleum asphalt,polymer-modified asphalt,liquid petroleum asphalt,coal tar distillation residues,or emulsified asphalt evaporation residues.It is the preferred instrument for highway and bridge construction and research institutions.
