Pneumatic DPL and DPM Testing Apparatus

Pneumatic DPL and DPM testing set is suitable for doing light (10 kg) and medium-heavy (30 kg) dynamic penetration tests according to ISO 22476-2 (replaces DIN 4094-3).

This pneumatic DPL and DPM testing set is a cost effective, simple and reliable tool suitable for light dynamic penetration testing up to approx. 10 – 12 m depth. It comprises of a pneumatic power-pack with a Honda fourstroke gasoline engine and maintenance-free air-compressor all integrated in a sturdy framework with carrying handle and a solid hammering unit with integrated air-cylinder. The unit holds a 10 kg (and an additional 20 kg) drop-weight and a fully automated pressure release valve. The air is led through the tubes of the framework where it can loose most of its warmth.

The bottom part of the hammering unit is in fact an anvil on which the drop-weight will fall. It is provided with a holder for the connection piece that goes on to the upper sounding tube.
