1. Usage
Extension—It is one of three indexes of scaling the bitumen, it is generally expressed by the ductility extent of bitumen, i.e. putting the bitumen sample with geometry form and size into aqueous medium with prescriptive temperature. The snapping length determined with the constant speed tension is called ductility of the bitumen in cm.
The automatic temperature control didgital display extension meter testing equipment is applicable for measuring the ductility to the materials such as various specifications and models of bitumen and liquid bitumen ,the residue after the liquid bitumen distillation, bitumen emulsion residue etc. It is widely used in the production, road construction, scientific research departments.
2. Characteristics
This instrument is composed by two digital displays. Digital display temperature controller can control and display the temperature in the cabinet directly. The fifth digital display can display the ductility length directly, and can automatically calculate the average ductility of three samples. It has the advantages of compact conformation, stainless, convenience to use, stable traction speed, small quiver, less noise, etc. The absolute and efficient Water Circle System can counterpoise and constant the water temperature and reduce the difference of the temperature to ensure the accuracy of controlling the temperature.
