Asphalt Penetrometers, Needle Penetration Test Equipment

Universal Asphalt Penetrometers test a wide variety of materials by penetration of weighted needles or cones and are all compliant with ASTM and AASHTO standards when fitted with proper needle or cone. The main applications are for bituminous materials, but these versatile instruments also work for waxes, greases, foods, and pharmaceuticals. Gilson offers heavy-duty units for manual and automatic use and lighter, portable models for fieldwork or users with a limited workload or budget.
