makes seismic acquisition faster than ever

The new PASI RADIO TRIGGER is a versatile and easy to use instrument designed for triggering a seismic acquisition via radio, by transmitting in the European band 869.4 ÷ 869.65 MHz (free license with no goverment taxes). PASI RADIO TRIGGER is particularly useful as an alternative to long trigger lead-in cables: the basic system consists of a transmitter Tx (to be conne...

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...

GFA down-hole 3D geophone has three 10Hz geophones - oriented according to the x-y-z axis -housed inside a cylindrical probe for the determination of the time of arrival of the type 's' and type 'p' seismic waves. The piston wall-clamping device can fit drilling well of a diameter between 50mm and 110mm (larger diameter on request). The mechanic clamping system with pneumatic piston can couple rigidly with the well casing, so to reflect seismic real signals at the best, avoiding the trouble of lacerating gasbags typical of most low-cost systems. The probe has a robust cylindrical metal case that can assure a long use in field conditions; the special signal cable (graduation 1m) and the air tube are delivered on a special reel, for a total weight of less then 15 kg (GFA-60).

Cable Lenght: 60/100 meters Data Inversion Software are also available.

Applications: shallow detailed investigations of pollutant plums in the ground; archaeological surveys; waste site deposit monitoring; mapping and monitoring of salty water contamination of groundwater reservoirs along coastal areas

Until now electrical imaging applied to geophysical exploration have been using the same traditional method for acquiring data: an electric continuos current was applied between two electrodes and the correspondent voltage was measured between other two electrodes inserted in the ground, with an inversion of polarity for each measurement. The new POLARES uses a sinusoida...

ANTEO is the expression of a new philosophy for a modular exploration seismograph.

The system consists of a single control & display unit (ANTEO CU) that works together one or more special cables (ANTEO AD6-x), each one with no.6x 24 bits A/D converters to be connected to any standard analogue geophone. This means that your system can grow from 6 to any number of channels with the simple addition of more AD6-x cables, available with different geopho...
