Manual penetrometer DPL

LIGHT DYNAMIC - PENETROMETER DYNAMIC PENETRATION TEST Hammering system for the control of trench or platform compaction (lost cone 10cm2) or implementation of ø32 mm probe for mini pressuremeter. Dynamic penetration tests are performed to determine the soil and rock in-situ resistance to a dynamic cone penetration. The Light Dynamic Penetrometer (DPL) with manual driving is the one allowing dynamic penetration tests with the lightest hammer (10 kg) in the whole range of dynamic penetrometers. DPL THE + Light, compact and handy Provided with transport case Dynamic penetration tests are performed to determine the soil and rock in-situ resistance to a dynamic cone penetration. The Light Dynamic Penetrometer (DPL) with manual driving is the one allowing dynamic penetration tests with the lightest hammer (10 kg) in the whole range of dynamic penetrometers The apparatus, hold by its handles, is maintained vertically . The constant falling height of its hammer (50 cm) drive the rods - fitted with a standard cone - into the soil. Penetration depth for a given drop number can be then measured thanks to rod graduations (every 10 centimeters). Soil failure resistance under the penetrometer cone is calculated with Dutch formula.
