Geotech Georig 220-11

Penetrometer Georig 220-11 is designed for static sounding CPTU and other field penetration tests like:

• Seismic sounding SCPT
• Conductivity and temperature
• Dynamic sounding DPT (light, medium, heavy)
• VANE test with full electronic registration
• Dilatometer test DMT
• Seismic dilatometer test SDMT
• Augering to 20 m
• Soil sampling

Standard includes:

• Automatic overload system protecting the cone against distortion/damage
• Penetrometer movement remote control system
• Rotary drilling head 2.4 kNm
