Overview and purpose

This instrument is suitable for measuring the elongation of asphalt and liquid asphalt distillation residue, asphalt lotion evaporation residue and other materials of various specifications and models. Widely used in production, road construction, and scientific research departments, it is more suitable for testing modified asphalt and meets the standards of the Ministry of Transport (JTG-E20-2011).

Characteristics

The LCD low-temperature extensometer is in line with the new generation of high-tech products, using an external screw and a linear guide for positioning, ensuring smooth stretching, high accuracy, and easy observation. The stretching operation system adopts a stepper servo controller. The control part adopts microcomputer processing, which can store 100 sets of data, display movement speed and precision temperature control, and provide a user-friendly operation page.
