Qualitest offers a versatile and high-performance range of Dynamic Probing and Standard Penetration Test (SPT) Rigs designed for accurate, in-situ geotechnical investigations. Our advanced models are engineered to perform dynamic probing tests including DPL, DPM, DPH, DPSH, as well as the Standard Penetration Test (SPT), in full compliance with ISO 22476-2, ISO 22476-3, and DIN 4094 standards.

With three distinct configurations available, our rigs cover a wide spectrum of field requirements—from lightweight, manually transported systems to powerful, self-propelled crawler rigs. These machines are ideal for contractors, geotechnical labs, and soil investigation firms looking for reliable and adaptable testing equipment.

The SPT series dynamic probing rig is a highly functional soil investigation machine that can be used for soil-bearing capacity tests, compaction tests and for soil sampling.
Adjustable dropping height and weight quality allow it to carry out multiple standards of dynamic probing tests. Because of the equipped rod extraction unit, taking out the probe rod or sampler becomes easy. Furthermore, it is versatilely suitable for working in confined spaces, and easy to transport due to the folding mast feature. These make it very helpful for the work on site.
