Introduction
This instrument is suitable for measuring the elongation of various specifications and models of
asphalt and liquid asphalt residues after distillation and asphalt emulsion evaporation residues. It is
widely used in production, road construction and scientific research departments, and is more
suitable for the test of modified asphalt. It meets the standards of the Ministry of Transport
(JTG-E20-2011).
Features
The liquid crystal low temperature extensometer conforms to a new generation of high-tech
products. It adopts an external lead screw and linear guide rail positioning, which is stable in
stretching, high in accuracy and convenient for observation. The stretching operation system
adopts a step servo controller. The control part adopts microcomputer processing, can store 100
sets of data
display the movement speed and precision temperature control, and the humanized
operation page.
