Universal Penetrometers

Universal 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. 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 field work or users with a limited work load or budget.
