Name：Intelligent Asphalt Extensibility Tester
Model：LYY-8
Specification
- Overview and usage
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 Communications (JTJ-E52-2011).
- Features
The LCD 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 electronic frequency conversion, stepless speed regulation, low noise, no running inertia, etc. The control part adopts microcomputer processing, can store 15 sets of data, display movement speed and precision temperature control, and humanized operation page.
