To ensure the stable operation of the force-measuring asphalt elongation measuring instrument, the instrument should be kept clean to prevent liquids or dust from entering. The force-measuring system should be calibrated regularly, and residual asphalt samples should be cleaned up promptly after use to ensure measurement accuracy and extend its service life.

Asphalt Ductility Elongation Tester

Model:LQJHU-0640

I.Product Introduction

The force-measuring asphalt elongation meter is a precision instrument used to determine the elongation performance of asphalt under tensile force.It measures the length of an asphalt sample stretched from its initial state to fracture by applying a controlled tensile force,thereby evaluating the flexibility and low-temperature crack resistance of asphalt.It is widely used in road asphalt quality control,modified asphalt research and development,and production process testing.
