An Asphalt Penetration Tester is a device used to accurately measure the penetration depth of a standard needle into asphalt under specified conditions to assess its hardness and consistency.

Product Name:Digital Asphalt Penetrometer

Model:LQ-GI001

Detailed Product Description

This instrument is designed and manufactured according to the technical requirements of T0604-2011 "Asphalt Penetration Test" and fully complies with the relevant provisions of the latest industry standard JTG 3410-2025 "Test Procedures for Asphalt and Asphalt Mixtures in Highway Engineering". It is suitable for determining the penetration of road petroleum asphalt, modified asphalt, liquid petroleum asphalt, and emulsified asphalt evaporation residues. It is an important piece of equipment for asphalt production enterprises, road engineering quality testing institutions, and research institutions to conduct asphalt performance evaluation.

This instrument also conforms to the following international standards:

ASTM D5/D5M-20 — Standard Test Method for Penetration of Bituminous Materials

EN 1426:2024 — Bitumen and Bituminous Binders – Determination of Needle Penetration (European Standard)

AASHTO T 49:2022 — Penetration of Bituminous Materials

The instrument has a reasonable structure, accurate and reliable measurements, and can meet the requirements of domestic and international standards for the uniformity, repeatability, and high precision of asphalt penetration testing.
