Lightweight penetrometer
The lightweight penetrometer is used to quickly measure the penetration resistance during soil investigations.

With help of a falling drop weight, the rod with screwed on cone is driven into the ground. Weight and falling height of the falling weight is defined.
Penetraion depth and the number of impacts is to be recorded. Dynamic probing can be executed quickly using this device.

It can also be used for testing solidity changes in the soil.

Rack for window sampler
A functional storage option for window sampler, extension rods, breaker hammers and tools.
Protects your equipment against dirt.

Easily folded to reduce space while transport.

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 executed and are suitable for testing solidity changes in the ground.

The compact compressor aggregate with only 16,4 kg weight and 4-stroke-HONDA-gasoline engine is mounted in a sturdy carrying frame and offers functional storage space for accessories and the penetrometer.

The impact 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 turn the device on or off.

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

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 investigaion. 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 by a hose with quick couplings. 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.

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

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

DPH-Caddy-Lifter can take up the penetrometer and transport it to the drilling point. Thanks to the four adjustable parking supports, the mast can be levelled in case of uneven ground. Thus rods can be vertically driven into the ground.

Using 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 pluggable support wheels in front and other parts plugged onto the DPC-Caddy-Lifter S-180 can be removed for transport. Transport weight is ca. 39,7 kg.

Recording device SON-P
Automated recording and valuation for dynamic probing according to DIN EN ISO 22476-2.

Time consuming counting and recording of impacts is no longer neccessary. By pressing a button the recording device SON-P does the work for you. Thanks to the included software, recorded data can be evaluated on PCand printed as protocol.

The device has a storage capacity for up to 250 records. Thanks to the Footswitch, allocation of impact rate per 10 cm is easily done.

Optional also available with printer.
