Lightweight dynamic probing
This lightweight device is used to quickly measure the penetration resistance during soil investigations.

With help of a falling weight, the rod with screwed on spike is driven into the soil. Weight and falling height of the falling weight is defined. Depth and blow count is manually recorded. It can also be used for testing solidity changes in the soil.

Advantage of the lightweight dynamic probing device is its low weight, solid construction and that it can be used by just one person.

Pneumatic-operated lightweight penetrometer DPL
This penetrometer is used for the dynamic probing light (DPL) to measure the penetraion resistance during soil investigations. Soil investigations can be quickly done and it is suitable for testing solidity changes in the soil.

The compact compressor-aggregate with only 15,6 kg weight and 4-stroke-HONDA-gasoline engine is mounted in a sturdy frame and offers practical storage space for accessories and the penetrometer.

The blow rate of the penetrometer can be adjusted via an easy accessible volume flow controller. Due to the integrated hand valve on the compressed-air hose one person can directly turn the device on or off.

Easy handling and its low weight offers high mobility at the terrain.

Compressor-aggregate E-DPL
An alternative to the gasoline version is this very lightweight aggregate with electric engine. This aggregate is only for the use with the lightweight penetrometer designed.

Pneumatic-operated heavyweight penetrometer DPH
This penetrometer is used for the dynamic probing heavy and medium (DPH and DPM) to measure the penetration resistance during soil investigaions. The 50 kg falling weight is pneumaitcally lifted at lifting height and falls down at the anvil, thereby transfers the energy to the rod.

The high-performance compressor-aggregate with gasoline engine is mounted in a sturdy carrying frame. This aggregate can be used for light, medium and heavy dynamic probing (DPL, DPM, DPH).

Penetrometer and compressor-aggregate are connected via a hose with quick coupling. All controls are easy accessible and clearly arranged.

By removing the 20 kg weight, the penetrometer DPH can be quickly converted to the penetrometer DPM.

Compressor-aggregate E-DPH
An alternative to the gasoline version is this aggregate with electric engine. This aggregate can be used for the lightweight, mediumweight and heavyweight penetrometer (DPL, DPM, DPH).

To make the transport easier, the frame has 4 attached wheels and a removeable drawbar.

Lost dynamic probing spike
The lost dynamic probing spike is slipped on the rod and when the rod is pulled out of the borehole, the spike remains in the hole.

Cone meter for probing spikes
According to DIN EN 22476-2 spikes used for dynamic probing must be checked for accuracy and be replaced when worn. The cone meter allows a quick control of the spikes without measurement.

DPH-Caddy-Lifter S-180
The practical DPH-Caddy-Lifter S-180 is a helpful addition for usage of the Stitz heavyweight penetrometer DPH.

It can be used to transport the penetrometer, as well as for the direct operation with the penetrometer.

DPH-Caddy-Lifter can pick up the penetrometer and transport it to the drilling point. Thanks to the four spindleable parking stands, the mast can be leveled in case of uneven ground. Therefore rods can be driven in vertically.

With help of a hand winch, the penetrometer is cranked up and then lowered onto the striking head screwed on the rod.

Due to the attached compressed air connection on the mast, the penetrometer can be switched on and off.

The front plug-in support wheels with brace and plugged parts can easily be removed for transport. Transport weight is ca. 39,7 kg.
