Temperature and speed regulating asphalt elongation tester

Temperature and speed regulating asphalt elongation tester model:LYY-11

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, it is more suitable for testing modified asphalt and is in line with traffic regulations（JTG-E20-2011）Standard.

2、 Characteristics

The LCD low-temperature extensometer is in line with the new generation of products, using an external ball screw and a linear guide for positioning, ensuring smooth stretching, and easy observation. The stretching operation system adopts electronic frequency conversion, which has no speed regulation, low noise, and no operating inertia. The temperature sensor and processing chip are used for accurate and reliable temperature collection.PIDThe technique ensures more accurate temperature control. The control module is processed by a microcomputer and can store data10Group data, display movement speed and temperature control, user-friendly operation page.
