Asphalt PenetroMeter

The asphalt hardness tester measures the softness or hardness of asphalt using the penetration method. A standard needle is vertically inserted into the asphalt sample under a fixed load and within a specified time, and the penetration depth is used to determine its consistency. It is used for road construction, quality control of asphalt materials, and aging performance evaluation.
Selection
Select the model with the appropriate penetration range based on the testing standards, taking into account temperature control accuracy and automation level. Verify the measuring range and resolution of the depth measurement mechanism, and confirm the load accuracy. Check whether the needle specifications comply with the regulations, and evaluate the data output method and calibration convenience.
