PASI s.r.l. products

GEA24 is a compact-sized 24 channel seismograph (2 units can be serialized for a total of 48 chs.) with a 24 bit data acquisition board and USB interface for external PC (not included in the standard supply). Suitable for so many applications, GEA-24 is a really affordable solution for all professional uses, as  Depth and Geometry of bedrock quality of rock, volume of excavation material, surveys in landfill elastic parameters of soil

SIS-911-050 with single clip. For MASW surveys (Rayleigh waves) - Re.Mi.

SIS-901-050 with single clip. For seismic refraction investigations.

SIS-907-050 with single clip. For seismic reflection investigations.

Horizontal Geophones 4,5 Hz. Ideal for multichannel analysis of surface waves (MASW).

SIS-902-050 with single clip and bubble level. For seismic refraction investigations.

GFA 50/100 3D borehole geo-phone is realized with 3x high sensitive geophones (nat.freq.10 Hz- 1 vertical and 2 horizontal sensors) oriented according to a triad of orthogonal Cartesian axes XYZ. Delivered with a cleat assembly to sustain its weight at the requested depth (GFA cable is graduated in meters), this borehole geophone has a pneumatic-mechanical clamping system.

Gemini-2 represent PASI  answer to the increasing request for HVSR acquisition: a single waterproof case with integrated a low frequency, high performing 3D-geophone assembly (two versions available, with real 2Hz sensors properly coupled) and a powerfull true 24 bit data acquisition board. Through Gemini USB interface and the related data acquisition software your PC will be transformed in a perfect, very high performing instrument for both data recording and post-processing analysis.

The 3D Land Geophone Mod. 3DLG-2 is the ideal accessory to add to your seismic instrumentation and perform HVSR, MASW and Vibration Analysis. One vertical and two horizontal high-performing sensors - with 2Hz resonance frequency and properly coupled - are mounted in a robust waterproof case, delivered with adjustable feet and inter-changeable spikes

Specially designed for small-scale cross-hole surveys, this compact hammer can be used to generate both P and S waves.The hammer can be downloaded using the steel cable and clamped to the requested depth by a pneumatic clamping system manually controlled by a lever from the surface; simply pushing up the steel cable to execute the first shot, the trigger installed on the energizer will start the acquisition for the “P/S”. After that you will have to drop the mass to make the acquisition with inverse polarity.
